Part 3.8: USB-to-Uart Bridge Connector

The AX7A035 FPGA development board includes the USB-UAR 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 for serial data
communication with a USB cable. The schematic diagram of the USB Uart
circuit design is shown in Figure 3-8-1:

Two LED indicators (LED3 and LED4) are set for the serial port signal, and
the silkscreen on the PCB is TX and RX, indicating that the serial port has data
transmission or reception, as shown in the following Figure 3-8-3
