Description: Last time we connected a pie to an electric motor, it made a mess of the kitchen. It turns out that raspberry pie is still a challenge for motors… Raspberry Pi, on the other hand, can totally hook up to all kinds of controls and sensors thanks to the PiFace Digital expansion board!
The PiFace Digital plugs directly into the GPIO port on your Raspberry Pi and adds a whole load of input and output capability. You can detect switch states, drive motors, move actuators, blink LEDs… you know, all the good stuff! Program it any way you want but there’s existing documentation for Python and Scratch! All of the input and output connectors are screw terminals, making it really easy to wire your Pi to all kinds of external systems. If you want to get an interactive project off the ground quickly with Raspberry Pi, the PiFace Digital is a great way to start.
Note: Though the PiFace is electronically compatible with the Raspberry Pi B+, the Raspberry Pi 2, and the Raspberry Pi 3, it can NOT physically stack on top of them.

Where does the 20v limit come from in the description. That’s not a limit of the listed relay. I want to run a 24vac motor at 1a. Any issue?
Great idea. Makes projecting come to life easier. I’d like to see a 40 pin version and more relays.
Hi, The 20V rating is found in the suppliers product page. http://www.piface.org.uk/products/piface_digital/ I wouldn’t recommend going over the spec rating. Happy hacking

There is no schematic or detailed data available to interface the expander to the new Pi-2.
I have not been able to make any use of the board.
Whats the problem with providing schematic or detailed data??????
As always Sparkfun delivered a product timely and professionally.
However, PiFace includes almost no documentation for this product. How is it helpful to make a product but include no instructions. Their website has almost no useful information to the function and wiring of the actual board. No information of what the 5 jumpers on the board do, or whether or not any GPIO pins are retained for use.
I don’t know if it will answer your questions, but there is some information to be found here: http://www.piface.org.uk/guides/.
