1. Power supply
You can apply power supply to
the board using
MINI-B USB
cable provided in the package.
On-board voltage regulators
provide the appropriate voltage
levels to each component of
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 MCP73832 enables you to charge the
