CH340G USB to TTL

The CH340G USB to TTL is a commonly used serial communication converter module that transforms a USB interface into a serial TTL signal for connecting computers to embedded devices or microcontrollers. It supports various baud rates and is compatible with both 5V and 3.3V operating voltages, making it suitable for debugging and programming development boards like Arduino and Raspberry Pi. The module features a USB interface and standard serial pins (TXD, RXD, GND, VCC). Once the driver is installed, it enables bidirectional data communication between the computer and the serial device, serving as a practical tool for embedded development and debugging.
