Part 6: USB to Serial Port

The AXKU040 FPGA development board is equipped with a Uart to USB

interface for serial communication and debugging of the development board.
The conversion chip uses the USB-UAR chip of Silicon Labs CP2102GM. The
CP2102 serial chip and the FPGA are connected by a level-shifting chip to
adapt to different FPGA BANK voltages. The USB interface uses the MINI USB
interface, which can be connected to the USB port of the upper PC for serial
data communication on the FPGA development board with a USB cable. The
schematic diagram of the USB Uart circuit design is shown below:
