Description
Microduino- RS485 is a low-power serial communication module based on MAX485 chip, which can achieve bidirectional serial port data transmission.
Features
With low power consumption, fast transmission rate and long transmission distance.
Operate in half-duplex mode and need only two lines.
Convert data receiving or sending automatically.
Capable of changing the TTL electric level to RS-485.
RS-485’s electrical feature: Logic “1” represents the voltage difference between the two lines–+(2—6) V; Logic “0” represents the voltage difference between the two lines–(2—6)V.
Combined with Microduino core or extension modules, you can select the serial port(Serial, Serial1, myserial（9，10）) through the dial switch.
