Wch: Uart To Kb-ms_v1.8

At its core, the WCH UART to KB-MS module serves as a protocol converter. It translates Universal Asynchronous Receiver-Transmitter (UART) signals—standard serial communication used by microcontrollers—into USB Human Interface Device (HID) protocols that a host computer recognizes as keyboard (KB) and mouse (MS) inputs.

Another significant application is in . Older industrial machinery often relies on proprietary controllers that output serial data. Modernizing these machines often requires integrating them with contemporary PCs. The WCH module allows the legacy controller to interface with modern PCs via USB keyboard/mouse inputs, effectively creating a bridge between aging equipment and modern computing infrastructure. Furthermore, it is widely used in KVM (Keyboard, Video, Mouse) switches , allowing a single set of peripherals to control multiple computers via serial signaling. wch uart to kb-ms_v1.8
