DFRobot RS485 Shield for Arduino UNO

This is an RS485 shield for the Arduino UNO. RS485 is an industry standard for long distance communication. Unlike RS422 which has a single driver circuit that cannot be disabled, RS485 drivers use three-state logic that allows individual transmitters to be disabled. This allows RS485 to implement linear bus topologies with only two wires.
