Support a variety of baud rate options, usually including 2400, 4800, 9600, 19200, 38400, 57600, 115200bps, etc., interface type: standard RS485 interface, with isolation function, can effectively prevent electrical interference, to ensure the stability and reliability of communication.

Communication protocols: It supports a variety of RS485-based communication protocols, such as MODBUS RTU, etc., and can interact with a variety of devices that support RS485 communication

Typically 5V DC power is provided by the connected CPU module, which consumes a small operating current and does not burden the CPU's power supply.
