That would be great, thank you. This tool has inspired me have a more serious go at integrating a pCP inside my amplifier. I've been tweaking my PCB design so that it will connect to the RPi either as a hat (should just about fit inside the official Pi3B case, or remotely via a ribbon cable. When attached directly as a hat, and mounted behind the amplifier front panel, it will also give me a convenient place to mount the RPi inside the enclosure. Here's my current draft of the PCB. The idea is that you'd connect each switch to a suitable GPIO pin using the 'GPIO Pins' and 'Switch Pins' pads, either by mounting rows of header pins and using jumper wires, or for a fixed installation they could be connected permanently by soldered flyleads. the prodtruding 'tongue' would carry a ribbon cable connector to allow other devices, such as a DAC, to be daisy-chained, or I might make it a snap-off section so that the whole board fits entirely withing the RPi case.
