Our friends over at LinkSprite have made this nifty little RS485 Shield, now you will be able to have a communication port for your field bus directly connected to your Arduino! Even though the RS485 is sometimes thought as an â€śarchaicâ€ť protocol, it will allow up to 32 devices to communicate through the same data line over a cable length of up to 4000ft with a maximum data rate of 10Mbit/s. Those arenâ€™t bad numbers!This version of the RS485 shield removes the optional DB9 connector bay and adds a second 2-pin screw terminal and the ability to choose two pins from your Arduinoâ€™s D0 to D7 as Software Serial Ports to communicate with the shield.This shield does come without its headers separate so a small amount of soldering will be required before attaching it to your Arduino device.Documents:SchematicDatasheet (MAX481CSA)RS485 Shield V2 TutorialProduct Wiki
