Description: 1. The CH340G is a low-cost, high-performance USB to RS232/RS485 converter that enables the connection of microcontrollers, computers, and other devices with serial communication interfaces using standard USB ports. 2. It comes with the CH340G microcontroller chip, which supports various baud rates (from 1200 to 1152K), data bits (5-8), stop bits (1 or 2), and parity checks (even/odd). 3. This USB to serial converter supports both RS232 and RS485 communication standards, making it versatile for various applications in industrial control systems, test equipment, data acquisition systems, and more. 4. The CH340G features a built-in 64-byte transmit and receive buffer, allowing efficient handling of large data packets and maintaining stable communication at high baud rates. 5. With its compact size (25mm x 14mm), low power consumption (<10mA), and simple plug-and-play installation, the CH340G is an ideal option for hobbyists and developers working on prototyping projects or building
