Adafruit libraries and example code for both SD and RTC mean you can get going quickly Prototyping area for soldering connectors, circuitry or sensors Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. & nbsp; Here & #39; s a handy Arduino shield: a lot of people are looking for a dedicated and well-designed data logging shield. Adafruit worked hard to engineer an inexpensive but well-rounded design. Not only is it easy to assemble and customize, it also comes with great documentation and libraries. The latest version of this popular shield has all the features of the popular original, and is "R3" compatible so you can use it with just about any Arduino or compatible. You can be up and running with it in less than 15 minutes - saving data to files on any FAT16 or FAT32 formatted SD card, to be read by any plotting, spreadsheet or analysis program. We even have a tutorial on how to use two free software programs to plot your data. The included RTC (Real Time Clock) can be used to timestamp all your data with the current time, so that you know precisely what happened when! Note: The RTC requires a small coin cell battery (not included). The board will still operate without the coin cell battery. Once installed, the battery will last for years. Item Specifics Dimensions (assembled): 70mm x 53mm x 17mm ( 2.7 in x 2in x 0.65 in) SD Card Format: FAT16 or FAT32 SD Card protrudes by 10mm ( 0.4 in) when inserted Weight: 22g/ 0.8 oz The RTC uses I2C 7-bit address 0x68.

Adafruit DC Motor and Stepper FeatherWing Add-on For All Feather Boards
Key Features: Completely stackable design: 5 address-select jumper pads means up to 32 stackable wings: that & #39; s 64 steppers or 128 DC motors! Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies 4 full H-Bridges: the TB6612 chipset provides 1.2A per bridge with thermal shutdown protection, internal kickback protection diodes. Up to 4 bi-directional DC motors with individual 12-bit speed selection & up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. Motors automatically disabled on power-up A Feather board without ambition is a Feather board without FeatherWings! This is the DC Motor + Stepper FeatherWing which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motors (or 1 stepper and 2 DC motors). The original Adafruit Motorshield Kit is one of our most beloved kits, which is why we decided to squish it all together on a FeatherWing to make something even smaller, lighter, and more portable! Instead of using a latch and the Arduino & #39; s PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers. You can use any DC or stepper motors that run from 4.5 - 13.5VDC and draw under 1.2A per coil. You & #39; ll likely also need to provide some external power supply for your motors, since its not suggested you run motors from the Feather & #39; s lipoly battery. Item Specifics 1 - Assembled & tested FeatherWing 5- Big 3.5 mm terminal block connectors 1- plain header Some soldering is required. Stacking headers, Feather and motors are not included Size: 50.8 mm x 22.9 mm x 1.6 mm / 2" x 0.9" x 0.06" Weight: 4.6 g Unlike the original full sized shield, there & #39; s no servo connections
Adafruit Standard servo - TowerPro SG-5010
Key Features: Rotates approx. 180 degrees (90 in each direction) Use any servo code, hardware or library to control this servo Good for beginners who want to make stuff move This high-torque standard servo can rotate approximately 180 degrees (90 in each direction). 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. Comes with 3 horns, as shown. 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. Position "0" ( 1.5 ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left. Note that the default servo pulse widths (usually 1ms to 2ms) may not give you a full 180 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75 ms to 2.25 ms. You can try shorter/longer pulses but be aware that if you go too far you could break your servo! Item Specifics Power: 4.8V - 6V DC max (5V works well) Average Speed: 0.2 sec/60degree (@ 4.8V ), 0.16 sec/60degree (@ 6V) Weight: 39g ( 1.37 oz) Torque: At 5V, 5.5 kg-cm / 76oz-in, and at 6V 6.5 kg-cm / 90oz-in.

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. Item Specifics Size: 3.0 x 0.6 x 0.3 Weight: 4.0 g

This is compatible with any camera mounting accessory, so if you need a solid attachment, you can use any camera positioning tool or tripod. Since it & #39; s crystal clear, you can see all the NeoPixels shining in glorious color. The light sensor also works just fine and the case will not block IR messages going in or out. Even though there are no microphone or speaker holes, audio passes through the case via various small openings - we tested it and the difference is barely noticeable. Item Specifics 2 molded plastic halves with the buttons in place Size (assembled): 55.5 x 52.6 x 16.3 mm Weight: 15.5 g Does not fit the older Classic Not waterproof or weatherproof No boards, cables, or accessories are included.
Adafruit HTU21D-F Temperature & Humidity Sensor Breakout Board
Key Features: Accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor - SHT15 Breakout I2C digital humidity sensor Breakout board that includes the Filtered version (to keep the sensor clean), a 3.3V regulator and I2C level shifting circuitry Fully assembled and tested - some basic soldering required It & apos; s summer and you & apos; re sweating and your hair & apos; s all frizzy and all you really want to know is why the weatherman said this morning that today & apos; 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 & plusmn; 2% with an operating range that & apos; 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 & plusmn; 1degC from -30~90degC. Such a lovely chip - so Adafruit came up with 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 & apos; ll need to solder the header onto the PCB but it & apos; s fairly easy and takes only a few minutes even for a beginner. Item Specifics Size: 18mm x 16mm x 2mm / 0.7" x 0.6" x 0.08" Weight: 1g I2C 7-bit address: 0x40
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 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!
Adafruit 3" Diameter Speaker - 8 Ohm 1 Watt

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

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!
Adafruit Mini Thermal Receipt Printer [ADA597]
Add a mini printer to any microcontroller project with this very cute thermal printer. Thermal printers are also known as receipt printers, theyand#39;re what you get when you go to the ATM or grocery store. Now you can embed a little printer of your own into an enclosure. This printer is ideal for interfacing with a microcontroller, you simply need a 3.3V-5V TTL serial output from your microcontroller to print text, barcodes, bitmap graphics, even a QR code! This package comes with a thermal printer including the print head (it does not require ink, a set of power and data cables, and two plastic shims for panel mounting. Thermal paper not included! The printer uses very common 2.25andquot; wide thermal paper , available in any office or stationery supply store. It can fit up to 50 ft of paper in the bay at once. You will also need a 5 to 9VDC regulated power supply, that can provide 1.5A or more during the high-current print - our 5V 2A power supply will work very nicely . We also suggest picking up a roll or two of 50and#39; long thermal paper , and also a 2.1mm jack terminal block adapter which will make it easy to connect the power adapter. We also have a starter pack that includes all the above We really like this printer because its easy to make Bold, underline , inverted text , variable line spacing, left/center/right justification, barcodes in 11 standard formats with adjustable height, and even custom bitmap graphics. Of course, we wouldnand#39;t leave you with a datasheet and a andquot;good luck!andquot; - We have a full tutorial and matching Arduino library that demonstrates the following: Printing with small, medium and large text Bold and underline text Inverted text Variable line spacingLeft, center and right justificationBarcodes in the following standard formats: UPC A, UPC E, E

Adafruit DRV8833 DC/Stepper Motor Driver Breakout Board
Key Features: Alternative to the TB6612 driver; better for low voltage uses Drive two DC motors bi-directionally, or one stepper motor ( 1.2 Amp or less of current) Comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project Built in current limiting up to 1.2 amp (or 2 amp for a short time) Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver; you get 2 full H-bridges(four half H-bridges) but this chip is better for low voltage uses (can run from 2.7V up to 10.8V motor power) and has built in current limiting capability. It & #39; s setup for 1A current limiting so you don & #39; t get more than 2A per chip, but you can also disable the current limiting, or change it to a different limit! DRV8833 is soldered onto a breakout board for you, with a polarity protection FET on the motor voltage input. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver! You also don & #39; t have to worry as much about burning out the chip with overdriving since there is current limiting. There & #39; s two digital inputs per H-bridge (one for each half of the bridge), you can PWM one of the inputs to control motor speed. Runs at 2.7V - 10.8V logic/motor power. The motor voltage is the same as the logic voltage, but logic voltage from 2.7V or greater will work so no need to worry if you are powering the motors from 9V and using 3.3V logic.

Adafruit DS3231 Precision RTC Breakout
Key Features: Integrated Crystal and temperature sensor keeps the timekeeping on schedule when the temperature changes Coin cell backup battery gives you years of precision timekeeping, even when main power is lost Great for datalogging and clocks, or anything where you need to really know the time The datasheet for the DS3231 explains that this part is an "Extremely Accurate I & sup2; C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that & #39; s all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up! ) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule. This is the finest RTC you can get, and now we have it in a compact, breadboard-friendly breakout. With a coin cell (required for battery-backup capabilities) plugged into the back, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time. Item Specifics Fully assembled and tested breakout 1 - small header Size: 23mm x 17.6 mm x 7.2 mm / 0.9" x 0.7" x 0.28" Weight: 2.1 g Some soldering required. CR1220 coin battery not included

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
Adafruit Push-button Power Switch Breakout
The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered by a push of the button. Press once to turn on, then press again to turn off. The circuit uses a 3A P-FET to connect and disconnect the IN pin to the OUT pin. Works great from 3V to 14VDC and up to 3A (although the FET gets a little toasty at continuous 3A draw) yet has only 0.5uA quiescent current draw. Using it is easy: connect the power source to Ground and IN, then the load from Ground to OUT. We include a 12mm tactile switch that works well but you can solder in your own switch as well. Press the button (or short the button pins) to alternate between on or off. A on-board red LED will light up when active so you know its working. There's a fourth KILL pin, which you can use to turn off the load and/or keep it off even if the button is pressed. When 1 or more volts is applied it will instantly turn off the FET. This allows your project to turn itself off. Comes with a assembled & tested bread-board friendly breakout board with four mounting holes, a 12mm tactile button, and some 0.1" male header you can solder to the board to plug it into a breadboard. The power switch is an elegant way to control power to your project, but there are some things to keep in mind: since there is a pass FET, this is only for 3-14V DC voltages. This is not a mechanical switch so there is no air-gap isolation. There is a 'body diode' in the pass FET so if the load has a voltage on it that is higher than the input voltage, current will flow back to the input. There is built-in debouncing but very bouncy switches can be annoying as they will turn on and off fast instead of latching. Adafruit Push-button Power Switch Breakout (11:52)Technical Details:Dimensions: 20.51mm / 0.8" x 17.75mm / 0.69" x 2.66mm / 0.1"Height with Switch: 8.69mm / 0.34"Weight: 2.6gMC14093 Datasheet (the NAND gate used) P-Channel Pass MOSFETSchematic!

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
adafruit stereo enclosed speaker set 3w 4 ohm
Listen up! This set of two 2.8" x 1.2" speakers are the perfect addition to any audio project where you need 4 ohm impedance and 3W or less of power. We particularly like these speakers as they are small and enclosed for good audio volume and quality. The pair have a handy SPK input cable to add audio to your displays (the connectors are similar to the JST-PH series whichis ~2.0mm spacing). We're specifically carrying these to use with our 10.1 inch , 7 inch , or 5.6 inch 1280x800 Display w/ Audio driver boards.

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 Rotary Encoder
Key Features: High quality 24-pulse encoder Panel mountable for placement in a box Soft-touch knob with an arrow in it Built-in push-button This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs. ) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great. This encoder also has a push-button built into it so you can press onto the knob to close a separate switch. One side has a 3 pin connector (ground and two coding pins) and the other side has two pins for a normally-open switch. Rotary encoders are useful as rotation sensors or selectors and look similar to potentiometers. However they are not like potentiometers at all, so it's important to realize the difference! These rotary encoders rotate all the way around continuously, and are divided up into 24 'segments'. Each segment has a click-y feeling to it, and each movement clockwise or counter-clockwise causes the two switches to open and close. There is no way to know what the current 'position' is - instead you would use a microcontroller to count how many 'clicks' left or right it has been turned. If you need to detect rotational 'position' a potentiometer would be a better choice.
Adafruit TCA9548A I2C Multiplexer
Key Features: TCA9548A 1-to-8 I2C multiplexer Get up to 8 same-address I2C devices hooked up to one microcontroller Simply write a single byte with the desired multiplexed output number to that port and bam - any future I2C packets will get sent to that port 3V and 5V compliant so you can use it with any logic level You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins! " Are you out of luck? You would be, if you didn't have this ultra-cool TCA9548A 1-to-8 I2C multiplexer! Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command. Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. Like all Adafruit breakouts, we put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level.

adafruit pro trinket 3v 12mhz
Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328. It's like an Arduino Pro Mini with more pins and USB tossed in. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. It has onboard USB bootloading support - we opted for a MicroUSB jack this time. We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. The Pro Trinket PCB measures only 1.5" x 0.7" x 0.2" (without headers) but packs the same capability as an Arduino UNO. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. However, it uses 3V logic and 12MHz clock. Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! Here's some things you may have to consider when adapting Arduino sketches: Pins #2 and #7 are not available (they are exclusively for USB) The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The onboard power supply is a 3.3V regulator and it can provide 150mA output You cannot plug shields directly into the Pro Trinket There is no Serial-to-USB chip onboard. This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. The USB connection is for uploading new code only. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28, 672 bytes. The bootloader does not affect RAM usage. UPC NO: 720189973321 SKU: ADIB00OG5AJCY
