RS485 Shield for Arduino focal length 35mm ARM and FPGA deviceDescription RS485 is an industrial standard for long distance, anti interference, and reliable communication. The Arduino RS485 shield, specially designed for the Arduino Uno board. It converts UART Serial protocol to the RS485 protocol. This RS485 board allows Arduino talk to industrial devices. In contrast to RS 422, which has a single driver circuit that cannot be switched off, RS 485 drivers use three state logic allowing individual transmitters
