Figure 3-6-1: Power input pin
If you need to debug the core board separately, power the core board
through the Mini USB port (J2) of the core board, the Mini USB cable is
connected to the USB port of the computer.
When the user supplies power to
the core board through the Mini USB port (J2), it cannot be powered through
the carrier board. Otherwise, current conflict may occur and the USB interface
of the computer may be burned out.
