Adafruit Standalone Momentary Capacitive Touch Sensor Breakout
Key Features: Single "momentary" capacitive touch sensor Red LED indicator when touched Save power by disconnecting the LED from the output pin Designed with the more-responsive "fast mode" This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. Just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is detected (e. g. a person touches the sensor-pad area) the red LED lights up and the output pin goes high. You can also solder a wire to the middle pad and create your own capacitive pad if the built-in one isn & #39; t suited to your project. If you want to save power, the LED can be disconnected from the output pin (cut the trace between the jumper marked as such). Designed with the more-responsive "fast mode", it draws about 0.5 mA. If you need ultra-low (~50uA) power usage, the mode jumper can be cut on one side & soldered closed on the other to fix it into that mode. Check Adafruit & #39; s datasheet for specific power usage measurements. Item Specifics Size: 20mm / 0.8" x 28mm / 1.1" Weight: 1.87 g
adafruit htu21df temperature & humidity sensor breakout board ada1899
It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HTU21D-F Temperature + Humidity Sensor - the best way to prove the weatherman wrong! This I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor - SHT15 Breakout It has a typical accuracy of 2% with an operating range that's optimized from 5% to 95% RH. Operation outside this range is still possible - just the accuracy might drop a bit. The temperature output has an accuracy of 1C from -30~90C. If you're looking to measure temperature more accurately, we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board. Such a lovely chip - so we spun up a breakout board that includes the Filtered version (the white bit of plastic which is a PTFE filter to keep the sensor clean), a 3.3V regulator and I2C level shifting circuitry. This lets you use it safely with any kind of microcontroller with 3.3V-5V power or logic. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.UPC NO:701980281617 SKU:ADIB00OKJFLWO

12mm Diffused Thin Digital RGB LED Pixels (Strand of 25)(WS2801)
RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can 'push' them into a 12mm drill hole in any material up to 1.5mm/0.06" thick. They're typically used to make outdoor signs. We also have flat-backed pixels that are essentially the same, but are not as long and thin.The pixels are connected by a 4-conductor cable. +5V (Red), Ground (Blue), Data (Yellow) and Clock (Green). Data is shifted down from one pixel to the next so that you can easily cut the strand or attach more onto the end.Each dot is digitally controlled, with an internal 8-bit PWM LED driver (24-bit color for 16 million different shades). The pixels must be clocked by a microcontroller, we have an example code linked below that works on an Arduino, it should be simple to adapt it to any other microcontroller.The pixels use 8mm diffused RGB LEDs, with a 120 degree beam width. The total max brightness of all LEDs is about 1600mcd but with the light more evenly distributed & mixed than a clear LED. (Please note: mcd ratings of LEDs are notoriously inflated by most LED sellers, so be extra-skeptical when reviewing LED ratings!)Sold by the strand, each strand has 25 pixels in series! Each strand has two JST SM 4-pin connectors so you can connect multiple strands in a row, as many as you wish, just watch for how much current they want. We now have LED pixel strands with the power wires (red & blue) spliced out so its really easy to connect 5VDC in using a 2.1mm jack terminal adapter. We have a 5V/2A supply that should be able to drive 2 or more strands and a 5V/10A supply that can drive up to 160 LEDs all lit up at onceIf you want to connect to the input of a strand (to wire it to power and a microcontroller) please get a receptacle connector. If you want to connect to the output, get a plug cable.You can drive these with an Arduino using any two microcontroller digital pins, check this library which also has example code to demonstrate the strands and be sure to read our very detailed tutorial on usage!Technical Details: 12mm diameter (0.45") 75mm deep (1.5") 80mm / 3" apart on the strand 25 pieces per strand New! These pixels use a WS2801 chip for full 24 bit color 5V power, 60mA maximum per pixel (LED on full white) 2-pin SPI-like protocol WS2801 Datasheet for the chip inside each pixel Brightness: Red = 3.3 Lumens/300 mcd, Green = 10 Lumens/1000 mcd, Blue = 2.7 Lumens/300 mcd (mcd calculation based on full 120 degree beam)
Adafruit FadeCandy - Dithering USB-Controlled Driver for NeoPixels
A new collaboration between Adafruit & Micah from Scanlime, we are excited to introduce Fadecandy, a NeoPixel driver with built in dithering, that can be controlled over USB. Fadecandy is not just hardware! It is a kit of both hardware and software parts that make LED art projects easier to build and better-looking so sculptors and makers and multimedia artists can concentrate on beautiful things instead of reinventing the wheel. It's an easy way to get started and an advanced tool for professionals. It's a collection of simple parts that work well together: Firmware that uses unique dithering and color correction algorithms to raise the bar for quality while getting out of the way of your creativity. Open source hardware for connecting cheap and popular WS2811 based LEDs to a laptop, desktop, or Raspberry Pi over USB. Fadecandy Server Software, which communicates with one Fadecandy board or dozens. It runs on Windows, Linux, and Mac OS, and on embedded platforms like Raspberry Pi. The Open Pixel Control protocol, a simple way of getting pixel data from your creative tools into the Fadecandy server. Libraries and examples for popular languages. We have Python and Processing already, with Javascript and Max coming soon. LEDs! Fadecandy works with Adafruit's popular WS2811/WS2812 LEDs. Each controller board supports up to 512 LEDs, arranged as 8 strips of 64 each. Headers are not included but we have tons of different kinds of dual header in the shop if you want to solder something into the pads. Fadecandy is designed to enable art that is subtle, interactive, and playful - exploring the interplay between light, form, and shadow. If you’re tired of seeing project after project with frenetic blinky rainbow fades, you’ll appreciate how easy it is to create expressive lighting! It's also battle tested! The firmware was originally developed to run the Ardent Mobile Cloud Platform, a Burning Man project which used 2500 LEDs to project ever-changing rolling cloud patterns onto the interior of a translucent plastic sculpture. It used five Fadecandy boards, a single Raspberry Pi, and the effects were written in a mixture of C and Python. The lighting on this project blew people away, and it made me realize just how much potential there is for creative lighting, but it takes significant technical drudgery to get beyond frenetic-rainbow-fade into territory where the lighting can really add to an art piece instead of distracting from it.
Adafruit Software Defined Radio Receiver USB Stick - RTL2832 w/R820T
Key Features: Easiest way possible to have fun with a powerful, configurable receiver Can tune into signals from 24MHz to 1850MHz Very compact (but very good quality) RTL2832+R820T module with an MCX RF connector Basic & #39; DVB-T & #39; antenna (not available in the US but will work in Europe) If you & #39; ve ever been curious about software defined radio (SDR), this USB stick is the easiest way possible to have fun with a powerful, configurable receiver. Packed with the powerful RTL2832U and R820T tuner, it can tune into signals from 24MHz to 1850MHz. That means you can use a computer (with Windows, Mac, or Linux) to tune into: FM Radio, AM signals (but not AM radio), CW (morse code! ), unencrypted radio signals (such as those used by many police and fire departments), POCSAG pagers, and more. Please note! Depending on your location, listening in to some radio signals may not be legal. So consider this your warning to check before & #39; accidentally & #39; tuning into naughty frequencies.

Adafruit Fingerprint sensor
Secure your project with biometrics - this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are typically used in safes - there's a high powered DSP chip that does the image rendering, calculation, feature-finding and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search. You can also enroll new fingers directly - up to 162 finger prints can be stored in the onboard FLASH memory. There's a red LED in the lens that lights up during a photo so you know its working. We like this particular sensor because not only is it easy to use, it also comes with fairly straight-forward Windows software that makes testing the module simple - you can even enroll using the software and see an image of the fingerprint on your computer screen. But, of course, we wouldn't leave you a datasheet and a "good luck!" - we wrote a full Arduino library so that you can get running in under 10 minutes. The library can enroll and search so its perfect for any project . We've also written a detailed tutorial on wiring and use . This is by far the best fingerprint sensor you can get.UPC:701851954671SKU:ADIB00QSIZSOG

Plastic Water Solenoid Valve - 12V - 1/2 NPT
Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. There are two 1/2" (Nominal non-taped National Pipe) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can push through. The valve has a gasket arrangement inside, so there is a minimum pressure requirement of 0.02 Mpa (3 PSI). Also, liquid can only flow one direction. We tried this solenoid at various DC voltages and found we could actuate it down at 6VDC (although it was a little slower to open). Here is the current draw table for various voltages. We suggest a TIP120 or N-Channel power FET with a 1N4001 kickback diode to drive this from a microcontroller pin. For a power supply, our 9V 1A or 12V 1A power adapters will do the job. If you want a beefier water valve, we also carry a brass version which does not have a minimum pressure requirement and can be used with liquid flow in either direction. Voltage Current6V 160 mA7V 190 mA8V 220 mA9V 240 mA10V 270 mA11V 300 mA12V 320 mAThese solenoids are not rated for food safety or use with anything but water.

Adafruit ADXL335-5V Ready Triple-axis Accelerometer (+-3g Analog Out)
Key Features: Fully assembled and tested Comes with 8 pin 0.1" standard header Two 2mm ( 0.08" ) mounting holes for easy attachment. The XYZ filter capacitors are 0.1 uF for a 50 Hz bandwidth Your favorite triple-axis accelerometer has been updated to now have an on-board 3.3V regulator - making it a perfect choice for interfacing with a 5V microcontroller such as the Arduino. This breakout comes with 3 analog outputs for X, Y and Z axis measurements on a 0.75" x 0.75" breakout board. The ADXL335 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices. The VCC takes up to 5V in and regulates it to 3.3V with an output pin. The analog outputs are ratiometric: that means that 0g measurement output is always at half of the 3.3V output ( 1.65V ), -3g is at 0v and 3g is at 3.3V with full scaling in between. Item Specifics Board size: 0.75" x 0.75" Mounting hole size: 2 mm VCC voltage: up to 5V Analog Outputs: Ratiometric XYZ Filter Capacitors: 0.1 uF for a 50 Hz bandwidth Fully Assembled
RF Development Tools Adafruit Feather 32u4 RFM69HCW Packet Radio - 868 / 915 MHz
- This is the Adafruit Feather 32u4 Radio (RFM69HCW) 900MHz - our take on an microcontroller packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 900 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GH z 802.15. 4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi. We have other boards in the Feather family, check'em out here. This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. We also sell a 433MHz version of the same radio chipset and if you want much longer range, check out the LoRa 900MHz Feather At the Feather 32u4's heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we've had tons of experience with as it's the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc. To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)

With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend! The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready). If you like Serial communication more than SPI, we also have a version that can talk UART The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here! Download our free Android/iOS app and you're ready to rock! Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.UPC:717520029113SKU:ADIB01F3U8V0W

Adafruit DC & Stepper Motor HAT for Raspberry Pi - Mini Kit
Let your robotic dreams come true with the new DC+Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control. Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins. In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include. Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time), a big improvement over L293D drivers and there are built-in flyback diodes as well. We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks. Install the easy-to-use Python library, check out the examples and you're ready to go! Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers onUPC:711978444085SKU:ADIB00TIY5JM8
Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor
Key Features: Updated in early 2020 to give a better range of values from soil moisture sensing I2C interface Determine your soil moisture via innovative capacitive measurement instead of resistive! No longer worry about your sensor oxidizing requiring repetitive re-calibration Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal. Even if they're gold plated! The resistivity measurement goes up and up, so you constantly have to re-calibrate your code. Also, resistive measurements don't always work in loose soil. This design is superior with a capacitive measurement. Capacitive measurements use only one probe, don't have any exposed metal, and don't introduce any DC currents into your plants. Adafruit uses the built in capacitive touch measurement system built into the ATSAMD10 chip, which will give you a reading ranging from about 200 (very dry) to 2000 (very wet). As a bonus, you see the ambient temperature from the internal temperature sensor on the microcontroller, it's not high precision, maybe good to + or - 2 degrees Celsius. To make it so you can use the sensor with just about any microcontroller, Adafruit added an I2C interface. Connect a 4-pin JST-PH cable (not included) to your microcontroller or single board computer to 3-5V power, Ground, I2C SDA and I2C SCL and load the code. No soldering required.

Add basic gesture sensing, RGB color sensing, proximity sensing, or ambient light sensing to your project with the Adafruit APDS9960 Proximity, Light, RGB, and Gesture Sensor. When connected to your microcontroller (running our library code) it can detect simple gestures (left to right, right to left, up to down, down to up are currently supported), return the amount of red, blue, green, and clear light, or return how close an object is to the front of the sensor. This device uses an I2C interface so it & apos; s easy to wire up and use. The APDS9960 from Avago Technologies has an integrated IR LED and driver, along with four directional photodiodes that sense reflected IR energy from the LED. Its proximity detection feature allows it to measure the distance an object is from the front of the sensor (up to a few centimeters) with 8-bit resolution. For your convenience, Adafruit placed the sensor on a PCB with a 3.3V regulator and some level shifting so it can be easily used with your favorite 3.3V or 5V microcontroller. SparkFun qwiic compatible STEMMA QT connectors are built - in for the I2C bus so you don & apos; t even need to solder! Just wire up to your favorite microcontroller or computer with a plug-and-play QT cable to light/color/proximity data ASAP. Item Specifics QT cable not included
Adafruit 1070 Short Flex Sensor
This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface. These sensors are easy to use, they are basically resistors that change value based on how much their flexed. If they're unflexed, the resistance is about ~25KO. When flexed all the way the resistance rises to ~100KO. They're pretty similar to FSRs so following this tutorial will get you started. You can use an analog input on a micro-controller (with a pullup resistor) or a digital input with the use of a 0.1 uF capacitor for RC timing. The bottom part of the sensor (where the pins are crimped on) is very delicate so make sure to have strain relief - such as clamping or gluing that part so as not to rip out the contacts!

Audio IC Development Tools Stereo 3.7W Class D Audio Amplifier (1 piece)
This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 3.7W channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.7V - 5.5VDC. Since the amp is a class D, its incredibly efficient (over 90% efficient when driving an 8O speaker at over a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic "LM386" amps! The inputs of the amplifier go through 1.0 uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are "Bridge Tied" - that means they connect directly to the outputs, no connection to ground. The output is a 360KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. Comes with a fully assembled and tested breakout board with 1.0 uF input capacitors. We also include header to plug it into a breadboard, 3.5 mm screw-terminal blocks so you can easily attach/detach your speakers, and a 2x4 header + jumper to change the amplifier gain on the fly. You will be ready to rock in 15 minutes! Speakers are not included, use any 3ohm or greater impedance speakers. UPC: 720189972874 SKU: ADIB00N42NP6W
Aluminum SMT Heat Sink - 0.27"x0.27" square
If you want to heat sink a SoC, motor driver, or other surface-mount package part, you might find yourself struggling to find a good heat sink. These sinks from Cool Innovations are beloved by our favorite engineers for their low cost, ease of use and low thermal resistance!The heat sink is a 0.27" x 0.27" (6.7mm x 6.7mm) square with four round 'fins' sticking out the top. The total height is 0.3" (7.6mm) but you can easily file it down if you need a shorter heat sink to fit in a case). Simply use thermal tape or a small amount of thermal paste to attach to the top of any flat chip. There is no thermal tape included with this product. Ideal for medium flat BGAs, TSSOPs, QFNs, etc!In still air, the thermal resistance is approximately 70ºC/WTechnical Details:Datasheet for Cool Innovations 3-020203U
Terminal Block - 2-pin 3.5mm - pack of 5!
Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy to adjust with a screwdriver, and not too chunky. The only down-side is that they do not fit into 2.5mm spaced holes (they're 3.5mm spaced) - but they do fit in most perf/proto-board if you rotate them diagonally (see photo above). They don't fit nicely into solderless breadboards.These terminal blocks are designed to 'snap' together. You can attach as many 3-pin or 2-pin ones along as you'd like to make arbitrary length of terminal block.So useful, we sell them as a pack of 5! Each order will net you 5 pieces of 2-pin connectors. Check out our 5 x 3-pin connector pack as well.Technical Details:Datasheet for 3.5mm terminal blocks

Adafruit Motor/Stepper/Servo Shield for Arduino v2.3 Kit
New! As of 3/21/2014 we are shipping motor shields with the terminal blocks, and power jumper pre-soldered on. You'll still need to do a little soldering to put on the shield-headers (or stacking headers) but it should be even easier and faster to get started! The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements: Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! What on earth could you do with that many steppers? I have no idea but if you come up with something send us a photo because that would be a pretty glorious project. Lots of other little improvements such as a polarity protection FET on the power pins and a bit of prototyping area. And the shield is assembled and tested here at Adafruit so all you have to do is solder on straight or stacking headers and the terminal blocks. Lets check out these specs again: * 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter! * 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC. * Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5 % resolution) * Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. * Motors automatically disabled on power-up * Big terminal block connectors to easily hook up wires (18-26AWG) and power * Arduino reset button brought up top * Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies * Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove. Works with Mega/ADK R2 and earlier with 2 wire jumpers. * Download the easy-to-use Arduino software library, check out the examples and you're ready to go! Comes with an assembled & tested shield, terminal block, plain header, jumper. Some soldering is required to assemble the headers on. Stacking headers not included, but we sell them in the shop so if you want to stack shields, please pick them up at the same time. Arduino and motors are not included but we have lots of motors in the shop and all our hobby servos, DC motors, and stepper motors work great.
Fixed Laser Mounting Stand
Use this nice fixed laser mount to attach any of our laser diode modules to your desk, robot, shark, etc. A set-screw holds the laser in place. Has a flat mounting plate with four holes for easy attachment and adjustment. Fits all of our modules. Laser not included. Technical Details: Dimensions: 35mm x 30mm x 18mm Mounting hole diameter: 3.5 mm / 0.14" Mounting hole pattern: Square 14.8 mm (along the length) x 23.8 mm (along the width) Fits lasers with up to 12.5 mm diameter ( 0.5" ) Weight: 22 grams
Small Reduction Stepper Motor - 12VDC 48-Step 1/16 Gearing
This is a great first stepper motor, good for small projects and experimenting with steppers. This uni-polar motor has a built in mounting plate with two mounting holes. There are only 32 step ( 11.25 degree) per revolution, and inside is a 1/16 reduction gear set. (Actually its 1/ 16.032 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32* 16.032 steps per revolution = 513 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw. A perfect first stepper motor and works well with the Motor Shield for Arduino. The gearing has a few side effects which are important to note. First, you can turn the stepper by hand but not as smoothly as an un-geared stepper. It also means you shouldn't use interleaved or micro-stepping to control or it will take forever to turn. Instead use single or double stepping. The torque is fairly high but its slower than un-geared steppers - we maxed out at about 80 RPM when powering with 12VDC and about 50 RPM on 9VDC. To use with the Adafruit Motor Shield, connect red to ground (middle), orange and pink to one motor port (say M1) and blue and yellow to the other motor port (say M2). So in order, thats: orange - pink - red - blue - yellow. Then just use the example code that comes with the Adafruit Motor Shield library and set the constructor to Adafruit_StepperMotor *myMotor = AFMS. getStepper(513, motornum) and the speed at 5 RPM by calling motor->setSpeed (5). Otherwise, you can also wire it up with some transistors and use the Arduino Stepper library (on the Arduino web site).

Micro Servo - High Torque Metal Gear
Add more power to your robot with this metal-geared servo. The tiny little servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds you're used to but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. Of course, its not nearly as strong as a standard servo. Works great with the Motor Shield for Arduino, our 16-channel Servo Driver, or by just wiring up with the Servo library. Comes with a few horns and hardware. To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE (see here for an example sketch). Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left.Technical Details:Size : 22.8 x 12.2 x 28.5 mmVoltage : 4.8V to 6V DCWeight: 13.4 gramsSpeed : 0.1 sec/60degrees (at 4.8V), 0.08 sec/60 degrees (at 6.0V)Stall Torque : At 4.8V: 1.8 kg-cm / 25 oz-in.

You'll need wire strippers, a soldering iron & solder, copper tape and heat shrink. A third-hand tool is really useful as well.Please note! EL tape, EL wire and EL panel are made with different processes - the color and brightness will not be consistent between the different types of EL products. The EL tape will not match the EL wire or EL panel exactly, they all will be slightly different colors.
Adafruit Black Shortening microSD Adapter for Raspberry Pi & Macbooks [ADA1763]
Adafruit Part Number: 1763 Stock Type: Raspberry Pi >> Accessories >> SD Cards In Stock & Ready to Ship Adding shortening to a Pi makes it fatter - but this kind of shortening makes your Pi a little slimmer! This black short-style microSD adapter slides in where the SD card goes but is 9mm shorter. This makes it stick out a lot less and makes for a more elegant (and less accident-prone) Pi. All you have to do is pop in a microSD card for a sleeker machine! The outer edge of the SD adapter has a deep grove for a fingernail to pull on for removal. Because its just a shorter microSD adapter, this short microSD adapter will work in any Raspberry Pi case ( our, other, low-profile microSD adapter card is a bit thicker and doesn't work in all cases, including the Adafruit Pi case and PiBows). Protrudes from edge of Raspberry Pi 8mm when installed This microSD adapter also worked great in our Macbook pro - load it up with a 64 microSD card and you've got a ton more storage, but without the sticking-out of a normal sized SD. MicroSD card and Raspberry Pi NOT INCLUDED We also have these in blue, pink, and green!

Adafruit 1304 Micro Lipo - USB LiIon/LiPoly charger - v1
Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.
Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the back, for when you'll only be charging batteries with 500mAh size or larger.
For use with Adafruit LiPoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.
Comes assembled and tested with a free bonus JST cable!
5V input via PCB-style USB connector
For charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)
100mA charge current, adjustable to 500mA by soldering a jumper closed
Free 2-pin JST cable included!
The MicroLipo charger can get hot during charging. Grab it by the sides and unplug then let cool before removing the battery - take care not to touch the components during charging!
Adafruit Small Enclosed Piezo w/Wires [ADA1740]
This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast movements like knocks. You can also use it under a drum pad to make a drum/crash sensor It's rated for up to 9Vpp use but you can also use 3V square waves and its plenty loud. For music use with an Arduino, check out the Tone tutorial . For sensing, the Knock tutorial is your guide! There are thin wires attached, we plugged them into a solderless breadboard, but they might too thin to plug in directly into the Arduino socket headers.UPC:701851952134SKU:ADIB00OKCR7EG

adafruit pid 3179 feather m0 rfm95 lora radio 433mhz
Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit Feather M0 RFM96 LoRa Radio (433 MHz) - our take on an microcontroller with a "Long Range (LoRa)" packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather M0 with a 433MHz radio module cooked in! Great for making wireless networks that are more flexible than Bluetooth LE and without the high power requirements of WiFi. This is the 433 MHz radio version. We also sell a 898/915 MHz version of the same radio chipset! At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This Feather M0 LoRa Radio uses the extra space left over to add an RFM9x LoRa 868/915 MHz radio module. These radios are not good for transmitting audio or video, but they do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee). SX1276 LoRa based module with SPI interface Packet radio with ready-to-go Arduino libraries Uses the license-free ISM bands (ITU "Europe" @ 433MHz and ITU "Americas" @ 900MHz) +5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software) ~300uA during full sleep, ~120mA peak during +20dBm transmit, ~40mA during active radio listening.

Adafruit Flora RGB Smart NeoPixel version 2 - Sheet of 20
Key Features: 20 pixels on a sheet Full 24-bit color ability with PWM taken care of by the controller chip Designed specifically for wearables Chainable design So, you want lots and lots of NeoPixels? And you want them for less? Not a problem! Here & #39; s a sheet of Flora NeoPixels fresh from the (reflow) oven. Cut them off as you need & #39; em and save a pretty penny while you & #39; re at it. We suggest cutting them out with diagonal cutters or heavy-duty scissors. What & #39; s a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like. They & #39; re easy to sew, and the chainable design means no crossed threads. These pixels have full 24-bit color ability with PWM taken care of by the controller chip. The driver is constant current so it & #39; s OK if your battery power changes or fluctuates a little. Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, the Flora can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). However, after about 10 pixels (or if the distance between pixels is more than an inch or two) the resistance of the thread can affect the power supply. For large quantities of pixels over 10, you may want to consider using stranded core wire or copper braid to provide a "power bus" for the pixels - the current draw will add up fast! Item Specifics Size: 0.5" ( 12.5 mm) diameter circle PCB Thickness: 0.1" ( 2.5 mm) total Speed Protocol: 800 KHz Power: 5-9VDC (can run at 3.5V but color will be dimmed) Constant current: 18.5 mA per LED (~55mA max total per pixel)
Adafruit NeoPixel Diffused 5mm Through-Hole LED - 5 Pack
Key Features: Diffused type Neopixel 5mm LEDs RGB LED with 4 legs Control the LED with high speed PWM for 24-bit color Fast and responsive with a milky-diffusing lens for a soft look If you like NeoPixel strips you & #39; ll love these 5mm diffused through-hole NeoPixels. All the single-pin-controlling-hundreds-of-LEDs goodness in a breadboard friendly format. Each LED looks just like a shorter version of the classic through-hole 5mm RGB LED with 4 legs, but instead of just red/green/blue there & #39; s a little chip inside that can control the LED with high speed PWM for 24-bit color. Power them with 5V and chain them together, tying the Data-Out pin of one to the Data-in of the previous one in the chain. If you & #39; re using an Arduino, you can control these LEDs with our wonderfully-written Neopixel library for Arduino. They also work great with Adafruit Trinkets. Note that these are "RGB" instead of "GRB" format used in the 5050-sized LEDs you are so used to. Check in the NeoPixel example code for how to swap the colors automagically. Item Specifics 5 pack of diffused-type LEDs Weight: 0.3 g May ship with either WS2812B or SK6812-based LEDs.
adafruit inductive charging set 5v @ 500ma max ada1407
The squarish board with two chips on it is the transmitter (power with 9V). The longer board is the output andyou can connect that to the part ofyour project that needs powering. Inductive charging is a way of powering a device without a direct wire connection. Most people have seen inductive charging in a rechargable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil. This is a basic charger set, and it does work, providing 5V DC output from the output half when the input half is powered with 9V to 12VDC. You can draw as much as ~500mA if the coils are 2 or 3 mm apart. If you only need 100 or 200mA you can be up 7mm apart. For 10mA draw, the coils can be up to half an inch ( 12.5 mm) apart. Any non-ferrous/non-conductive material (eg air, wood, leather, plastic, paper, glass) can be used between the two coils. The material doesn't affect the distance or efficiency. The coils do need to be fairly co-axial, try to get them to be parallel and have the circles line up for best power-transfer. (This is why the electric toothbrush must fit into the plastic holder, it's lining up the two coils for best efficiency) Because its an air-core transformer, it's fairly inefficient. Only about 40% of the energy in shows up on the other end, but for low power or charging project. If you draw 5V 100mA on the output side ( 0.5W ), you'll need 0.5W * 2.5 / 9V = ~150mA from the input end. The quiescent current is about 70mA at all time, even when the other coil is not anywhere near by. These are basic modules, probably used for some low cost toy. We don't have any datasheets or specifications for them. We do see a feedback resistor divider on the output side using 06 UPC NO: 711978441954 SKU: ADIB00SLYAIG8
Lithium Ion Battery - 3.7v 2000mAh
Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 2A or less (500mA is best). We suggest a Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge. Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1 C or even less - 100 to 500mA is a good rate, and available from any USB port if using a USB-powered charger Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. Never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits. Polarity matches all Adafruit LiPoly/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all Lithium ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies
Arcade Button - 30mm Translucent Pink
A button is a button, and a switch is a switch, but these translucent arcade buttons are in a class of their own. They're the same size as common arcade controls (often referred to as 30mm diameter) but have some nice things going for them that justify the extra dollar. First, they look fantastic, all 6 colors have a crystal translucent glossy look. Although they do not have LEDs built in, we're confident that sticking a diffused LED into the body would make it light up very nicely. They are also shorter than cheap arcade controls, and snap into place, so you only need 1.5" of depth ( 1.25" if you bend the contacts over). The button action is smooth, without a strong click, yet you can definitely feel when the button is pressed. A tiny micro-switch is pre-installed, with gold plated contacts. A button is a button, and a switch is a switch, but these translucent arcade buttons are in a class of their own.

Hey Mr. DJ! Turn up that Raspberry Pi mix to the max with this cute 3W Stereo Amplifier Bonnet for Raspberry Pi. (It's not big enough to be an official HAT, so we called it a bonnet, you see?) It's the exact same size as a Raspberry Pi Zero but works with any and all Raspberry Pi computers with a 2x20 connector - A+, B+, Zero, Pi 2, Pi 3, etc. We've tested it out with Raspbian (the offical operating system) and Retropie. This Bonnet uses I2S a digital sound standard, so you get really crisp audio. The digital data goes right into the amplifier so there's no static like you hear from the headphone jack. And it's super easy to get started. Just plug in any 4 to 8 speakers, up to 3 Watts, run our installer script on any Raspberry Pi, reboot and you're ready to jam! Each order comes as a fully tested PCB with a 2x20 header and 2x terminal blocks. Some light soldering is required to attach the header onto PCB so you can plug it into your Raspberry Pi. Once that's done either plug one of our enclosed speaker sets right into the JST jack in the middle or you can solder the terminal blocks in and then connect any speaker you like like our 4 3W or 8 1W. Hey you can even use a surface transducer! Our tutorial will get you set up with instructions, you'll be rockin' out in 15 minutes. Don't forget to make sure you have a good strong 5V power supply - especially if you're using the 3W 4 ohm speakers! Our 2.4A power plug is recommended.

Fast Vibration Sensor Switch (Easy to trigger) Adafruit 1766
The "poor man's" accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft spring coiled around a long metal pin. When the switch is moved, the spring touches the center pole to make contact. So, when there's motion, the two pins will act like a closed switch. When everything is still, the switch is open. Great for basic projects and wearables!
