RS485 Shield V3 - Raspberry Pi

Our friends over at LinkSprite have made this nifty little RS485 Shield V3 for the Raspberry Pi, now you will be able to have a communication port for your field bus directly connected to your RPi! Even though the RS485 is sometimes thought as an €œarchaic€ protocol, it will allow up to 32 devices to communicate through the same data line over a cable length of up to 4,000ft with a maximum data rate of 10Mbit/s. Those aren't bad numbers!

This shield comes pre-assembled so all you will need to do is just snap it right onto your Raspberry Pi and get programming. The RS485 Shield V3 is compatible with Raspberry Pi B, B+ and Raspberry Pi 2.

Note: The shield has an unpopulated footprint for a DB9 connector. Check below if you need to add the connector. Otherwise you can use the screw terminals.
