1. Power supply
Ready for XMEGA board can be powered in two ways: via USB connection, or using external power sources such as adapters and
laboratory power supplies. USB connection can provide up to 500mA of current which is more than enough for every on-board module
and for operation of the microcontroller. If you decide to use external power supply, you can choose between AC/DC adapter connector
or power screw terminals. Voltage values must be within
7-23V AC
or
9-32V DC
ranges.
Power LED (GREEN)
will indicate the presence
of power supply. Use only one of suggested methods for powering the board.
