Introduction

AI Translation

CH9328 is a serial UART to HID keyboard chip that is identified as a standard USB HID keyboard device on computers. CH9328 supports one-way data transmission, it can receive the serial UART data (such as ASCII code), and according to the HID keyboard device specification, the data is packaged into a standard keyboard code and uploaded to the computer through the USB port. Through the provided Windows software, the user can also configure the chip's VID, PID, and various string descriptors.
