Part 3.9: USB to Serial Port

The AXU7EV 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:
