Description:
CH340 is a USB bus converter chip that can realize USB to the serial interface. CH340 supplies a common MODEM liaison signal used to enlarge the asynchronous serial interface of a computer or upgrade the common serial device to the USB bus direct system. This USB to RS485 converter uses the high-performance CH340 chipset and is compatible with all the latest operating systems. It can be applied to various types of industrial applications.
CH340 is a USB bus conversion chip, it can realize USB to UART interface or USB to printer interface. In serial UART mode, CH340 provides a common MODEM liaison signal, used to expand the UART interface of a computer or upgrade the common serial device to USB bus directly.
USB to serial adapters are devices that convert the data sent by a serial-enabled device for use by a USB port. The serial end has a DB9 connector, which plugs into the serial device. The USB connector plugs into the computer's USB port or a connected USB hub.
CH340 chip operates with a minimum amount of components and it has a full-duplex serial interface with internal FIFO. Its Baudrate is about 5bps tp 5Mbps. 
This module includes some features like small size, low cost, refined simple design, high reliability make it to an ideal serial port conversion module.
