Part 3.7: USB to Serial Port

The AV7K325 carrier board is equipped with a Uart to USB interface for

system debugging. The conversion chip adopts the USB-UAR chip of Silicon
Labs CP2102GM, and the USB interface adopts the MINI USB interface. It can
be connected to the USB port of the upper PC with a USB cable for
independent power supply of the core board and serial data communication.

The schematic of USB Uart circuit design is shown in the figure below:
