Thanks for the suggestion Bob.

I should have mentioned that the breadboard design in the photo is done with a Pi 3 and it certainly made life a bit cheaper and easier for testing things out!

One problem in a metal footswitch design is that ideally the Pi will be encased within the footswitch enclosure. I suspect that won’t be good for the onboard WiFi chip signal and there doesn’t seem to be a way of bringing out an antenna from the chip?

Hence the suggestion of a Pi Zero with a USB WiFi dongle (with antenna), so that could be mounted outside the box? . . . and with the Pi Zero, the cost is also kept down. One problem with the Pi Zero is it doesn’t have an ethernet connector which is a nice backup if the venue causes any problems with the WiFi signal – swings and roundabouts as usual!
