Pi-Face Relay Plus boards.

KenKen Posts: 48New Member
I am also looking for information if anyone has tried the Pi-Face Relay Plus hats which provide 4 (or 8 with add-on extra boards) relayed outputs -or- 4 relay and 4 motor control outputs and can be stacked up to 8 high to combine to 64 outputs. They also provide alternate terminal block connections for powering a Pi which I also don't know if it's possible to power an UP! Board through the GPIO header this way.

    Hi Irwin

    The UP board can be powered through the 5V pins of the GPIO header.

    I haven't tried to use the PiFace Relay+ with the UP board myself. But I took a quick look through their Python scripts on github just now, and I can't see any obvious reason why it wouldn't work.

    You will probably need to make a small change here though to use "/dev/spidev2.0" (instead of "/dev/spidev0.0") on the UP board:
    https://github.com/piface/libmcp23s17/blob/master/src/mcp23s17.c#L19

    Also, you'll need to be using one of the supported kernels for UP, either ubilinux or Ubuntu, available from the Downloads section: https://up-community.org/downloads
