This was my first attempt at making a cheap squeeze client for multi room audio using https://github.com/sle118/squeezelite-esp32 I used the ESP32-A1S to avoid having to solder too many SMD parts. This was a mistake as the A1S is a massive pain to work with. This board also has a fair amount of digital noise and I'm too inexperienced to determine if its the board design or the A1S.
I suggest you do not use this version and use my next revision.
