“Nice product, fits like a glove on the Pi Zero. I already had a Pi Zero/W set up with the Phat Dac and Volumio. Replaced it with this one, then all I had to do was add the 'gpio=25=op,dh' to config.txt and it worked straight away. It is hooked up to an old receiver on the Aux input.
Will try with the Mopidy package to compare features but for now, it does the job!”
