Detailed Review:

This is the first time that I have been lucky to get onto a road test. After an initial wait due to supply issues I was very excited when my device finally landed on my door step.


It comes in a nice small box but sadly, at the time I got mine, it had no documentation and no link to anything. Although the first time I look I failed to find anything a few weeks later with more time on my hands it appeared that teh whole wolrd was starting to play with the device. Installation, connection and basic programming instructions can be found at


Its profile is a match for the Pi and pushing it onto the GPIO pins is not too tight but certainly feels secure. The device (the relays) increase the overall height by approx 15 mm. This should make it very easy to find a case for it. Pictures below show the device, how it fits on teh Pi and then with everything connected.




Following the instructions in the PDF, using my Raspian os that I had already set up was very easy and everything was up and running very quickly. A simple run of the command "piface/scripts/piface-emulator" and the emulator was up and running.


Press the override button and you can then test everything is working correctly. Output pin 0 and the appropriate led should light up. It s a nice way of checking that you have installed everythign correctly and that the device is operating.image



More to come on this road test soon.....
