I have finally finished routing a PCB for a BrewPi Arduino shield! It took a bit longer than expected.
I posted it on the forum, so head over to the forum and please check my work for errors, so I can go to manufacturing as soon as possible.
You soon will be able to buy this shield as a bare PCB, with SMT soldered, or fully soldered. This is a first step to making BrewPi a bit more plug and play.
