DFRobot RS485 Shield for Arduino - Industrial Serial Bus screw it doesn't need to addBuild Faster with the RS485 Shield for Arduino Arduino RS485 is an industrial standard for long distance, anti interferrence and reliable communication. So we create this RS485 Arduino shield, especially designed for the Arduino controller board. It converts UART Serial protocol to RS485 protocol. This RS485 board allows Arduino access to industrial standard protocol easily. In contrast to RS 422, which has a single driver circuit which cannot be
