Adafruit PowerBoost 500 Shield - Rechargeable 5V Power Shield

Key Features:

• Optional On/Off switch included
• Comes as a kit of parts
• Onboard boost converter provides at least 500mA current (1A peak)
• Compatible with Arduino Uno, Duemilanove, Mega, Leonardo and Due

What' s a project if it' s trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield! This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster. Compatible with basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used. You can stack shields on top, or stack the PowerBoost on top.

The PowerBoost shield can run off of any Lithium Ion or Lithium Polymer battery ( 3.7 / 4.2V kind) but we suggest 1200mAh capacity or 2000mAh capacity batteries, both of which fits very nicely in the empty space of the shield. Plug in the battery and recharge it via the microUSB jack. When you' re ready to go, just unplug the Arduino from USB or the wall adapter and it will automatically switch over to shield power. There' s an onboard fuse to protect against higher current draws which could damage the boost converter or battery.

There' s even an optional switch. If you choose to solder it in, it will let you turn the shield and Arduino power on/off.

Item Specifics
Size: 2.1" x 2.7" x 0.08"
Height w/ JST: 0.3"
Weight: 12.5 g
Use only Lipoly batteries with protection circuitry
Some light soldering is required
Battery, wall adapter, and USB adapter are NOT included
Compatible with Arduino Uno, Duemilanove, Mega, Leonardo and Due
Not recommended for driving motors or robots where the stall current can cause high current spikes
Note: Powerboost does not pass through the ICSP headers (the battery is in the way. If your stacking shield uses ICSP for data transfer, you' ll need to stack the PowerBoost above it!
