Microduino- RS485 is a low-power serial communication module based on MAX485 chip, which can achieve bi-directional 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.
-
Standard UPIN27 interface.
Specification
-
Power supply: 5V and 300μA.
-
Adopt half-duplex communication mode, which can send or receive data at a time.
-
Transmission rate up to 2.5Mbps.
-
Convert data receiving or sending automatically or with program.
