Short Description
The CH340C is a low-cost USB-to-UART (TTL) bridge IC designed by WCH (Nanjing QinHeng Electronics).
It serves as a dependable interface between a USB host and a serial UART device, allowing for simple communication with microcontrollers, development boards, embedded systems, and serial peripherals.
Unlike the CH340G, the CH340C has an internal crystal oscillator, which eliminates the requirement for an external 12 MHz crystal and reduces the component count.
The gadget provides full-speed USB 2.0 connectivity and works with Windows, Linux, and macOS via widely available drivers.
The CH340C is frequently utilized in Arduino-compatible boards, ESP8266 and ESP32 development boards, USB-to-serial adapters, industrial controls, and embedded applications that need USB serial connectivity.
