1. Power supply
You can supply power to the board with a
Mini-B USB cable provided in the package.
On-board voltage regulators provide the
appropriate voltage levels to each component
on the board. Power LED (GREEN) will
indicate the presence of power supply.
You can also power the board using a Li-Polymer
battery, via on-board battery connector. On-board
battery charger circuit enables you to charge the battery
over USB connection. LED diode (RED) will indicate
when battery is charging. Charging current is ~300mA
and charging voltage is 4.2V DC.
