The CH340G Module USB to TTL/Serial Converter is a versatile and high-performance solution that simplifies serial communication. This compact module provides a full-speed USB interface that is compatible with the USB 2.0 standard, making it easy to add serial ports to your PC or upgrade existing serial port devices. With a crystal and just a few capacitors, this converter operates with minimal external components, saving you time and money.

The CH340G module provides a virtual serial port, enabling you to use existing applications that require serial ports without the need to modify existing code. The module supports a range of baud rates, from 50 bps to 2 Mbps, and includes a hardware full-duplex serial interface with an internal FIFO. It also supports a range of common flow control signals, such as RTS, DTR, DCD, RI, DSR, and CTS, and is compatible with RS232, RS422, and RS485 with external level shifting components. The CH340G Module USB to TTL/Serial Converter is easy to use and operates with a 5V and 3.3V power supply, making it an ideal solution for a wide range of applications that require reliable and efficient serial communication.
