Power Supply
The target board is powered from the PC USB port, through which winIDEA (IDE) running on a PC, connects to
the on-board integrated debugger. Connection is made using a standard USB cable. Battery power supply for
RTC can be optionally connected to P11 (see P11 description for more details).
