This is an RS485 to UART (3.3V 5V TTL) Conversion module. With high-speed switching switch, automatic switching between sending and receiving, no additional control port is required, and it can support baud rate up to 256000BPS. The RS485 interface comes with TVS anti-surge protection. It is an ideal converter module for MCU to access RS485 network.
