The AT32UC3C-EK offers four interfaces to power the board, from the USB Virtual
Com Port (USB VCP) interface, from the USB USER interface, or from an external
source connected to the J1 or J2 headers. If two power sources are applied at the
same time the following priorities are used to select the current valid power source:
That means that if the board is connected to a USB host it has the highest priority and
will therefore serve as current power supply. Other power supplies that are connected
to the board at the same time will be ignored.
The input range on the external power supply header is from 3.3V to 5V for J2 and
from 9V to 12V for J1.
To power the board from the USB VCP or from the USB USER connector, use the
“Mini-B plug to std-A plug 1.5m USB2.0” cable that is included in the kit and connect it
between the host and the board USB VCP connector.
When the board is powered, the green LED (marked with “POWER”) will light up and
the default board firmware will start to run.
More information about the different power inputs is available in the hardware user’s
guide.
