DFRobot RS485 Shield for Arduino

RS485 is an industrial standard for long dsitance, anti-interferrence and reliable communication. So we

create this RS485 shield, especially designed for the Arduino controller board. It can easily convert

UART/Serial protocol to RS485 protocol. This board allows Arduino access to industrial standard

protocol easily.

Features

• Integrated a standard RS485 port ,a mini RS485 port, RS485 headers

• Provide the welding areas to make full use of the free space. And more importantly, it's

convenient for your DIY design.

• Switch between automatic mode and manual transmission mode, which expand the scope of

application.

• Besides Tx/Rx interface, there is a switch to block/disable this shield, when Arduino needs to be

programmed.

• Gold immersion PCB. Long pins on the back adapt to most Arduino controllers.

Specifications

• Power module: +5V

• Module size: 55mmx53mm

• 16 digital IO port (including a I2C interface)

• 6 analog IO port and power

• Operation and programming mode switch
