Product Overview

RS485 Shield for Arduino is an industrial standard for long distance, anti-interference and reliable communication. It is 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 switched off, RS-485 drivers use three-state logic allowing individual transmitters to be deactivated. This allows RS-485 to implement linear bus topologies using only two wires. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices. Besides Tx/Rx interface, there is a switch to block/disable this shield, when Arduino needs to be programmed.
  • Integrated a standard RS485 port, a mini RS485 port, RS485 headers
  • Provide the welding areas to make full use of the free space
  • Switch between automatic mode and manual transmission mode which expand the scope of application
  • PH2.0 sensor interface for DFRobot RS485 series sensor (URM04 Ultrasonic sensor)
  • Gold immersion PCB, long pins on the back adapt to most Arduino controllers
  • 5V power module
  • 16 digital IO port (including a I2C interface), 6 analogue IO port and power
  • Operation and programming mode switch
  • Standard RS485 interface, mini RS485 interface and RS485 pins, welding area, reset switch
  • Module size is 55mm x 53mm (2.16"x2.08")
