USB to 8-channel serial port based on Qinheng CH348Q

Overview

The USB to 8-way serial port module designed based on Qinheng's CH348Q chip does not require additional programs. It supports both win system and Linux system. The driver has been placed in the Lichuang accessory.
Each serial port has indicator lights to increase the convenience of use.
Because I usually use this tool to adjust programs, my USB interface uses a TYPE-B interface, which is more durable and stable.
Each serial port of the development board has TX and RX indicator lights, which will be very convenient during debugging.
