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.
Boosted shield output rail for Arduino, Adafruit Learn states the boost section takes 3-4V LiIon/LiPoly input and boosts it to 5.2V before a Schottky diode drops it to about 5V.
Ground reference for the PowerBoost shield and stacked Arduino.
LiIon/LiPoly battery input via the shield battery connector; Learn describes 3-4VDC input from the battery into the boost section.
Micro USB connector used to charge the battery; Adafruit Learn says plugging Arduino USB will not charge the battery and the shield microUSB charge rate is up to 500mA.
Optional booster enable switch connection. Learn states a custom switch can be soldered to the middle pin and the pin right below it; the switch carries signal, not power.
Analog · about 5V output, can dip to 4.8V over 1A; 500mA fuse on boost output · 0V
Verify supply voltage and logic levels before powering up.
Module pins: 5V output, BAT / JST battery input, Micro USB charge input, GND, Battery monitor solder jumper. Schematik maps them to your board in the app.
