Part 7: USB to serial port

For the AC7021B core board to work and debug separately, we have a
Uart to USB interface for the core board. Used for separate power supply and
debugging of the core board. The conversion chip uses the USB-UART chip of
Silicon Labs CP2102GM. The USB interface uses the MINI USB interface. It
can be connected to the USB port of the upper PC with a USB cable for
separate power supply and serial data communication of the core board.
