SparkFun Support and Front Desk will be closed on Thursday 11/14 from 1-2:30pm for a company event. Please plan to pick up your orders before or after this timeframe.
Our friends over at LinkSprite have made this nifty little RS485 Shield 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 "archaic" 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 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.
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.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
