CH9328 verification version

A board that can be used for WCH's 9328. It has a USB male port that can be directly plugged into the computer.

With 4 configuration switches for modifying the corresponding IO switching chip functions

Lead out a pair of serial ports for connection with the microcontroller. You can use the microcontroller to simulate HID devices to perform some strange (?) operations.

The 3232 next to it is used as a positive and negative power supply. You can delete it if it is not needed (it is actually for the purpose of joining the boards)

Please see the schematic diagram for specific precautions.

If the LED is too blind, you can increase the series resistance

--------

According to the official manual comparison, this board can be used for CH9326, CH9328, CH9329 and other HID series chips. Friends who have the goods can try it by themselves.
