DIY Eurorack Synth Stuff

BreakOut Development Board

A simple breakout board to help development of Eurorack modules. Clips on your breadboard and provides a power connector, power indicator lights and some I/O terminals. It also has two selectable ground rails, so if you want one or both inner rails connected to something other that ground, you can.


  • 4 IO ports
  • Power indicator led for both +12v and -12v rails
  • Selectable ground rails


Schematics & BOM


This project was kindly sponsored by PCBWay They offer a fast and very affordable PCB manufacturing service. I find that their ordering process is very intuitive and the boards are of exceptional quality, so I highly recommend them.
