Overview
CH9329 is a UART to standard USB HID device (keyboard, mouse, custom HID) chip. According to different operating modes, it can be identified as the standard USB keyboard device, USB mouse device or custom HID device on the computer. CH9329 receives serial port data sent from the client and according to the HID device specification, the data will be packaged and then transmitted to the computer via USB port. Though the provided computer software, users can also configure the chip operating mode, serial communication mode, serial communication baud rate, various timeout periods, VID, PID, and various USB string descriptors.
