Part 3.6: USB to Serial Port

The AXU15EG carrier board is equipped with two Uart to USB ports, one is
connected to the PS end, and one is connected to the PL end.
The conversion chip uses Silicon Labs CP2102GM's USB-UAR chip, and
the USB interface is a MINI USB interface. You can use a USB cable to
connect it to the PC's USB port for serial data communication. The schematic
diagram of the USB Uart circuit design is shown in the figure below:
