This module uses single cell LiPo batteries ( just like the ones sold on sparkfun ). It seamlessly switches between USB power and battery power. The on board gas gauge tracks battery life, charging, voltage, current, and temperature. It can trigger events for overtemp, over/under charge, under/over voltage. Can be switched to high current charge when >500mA is available.
Supports program and debug of gadgeteer over USB.
Compatible with D type sockets on .Net Gadgeteer mainboards.
