From the project

A Eurorack Bus Board that has 8 outputs

A Eurorack bus board with 8 module slots, distributing ±12V + GND across multiple connector formats. The project has three PCB variants in the same KiCad project: 10-pin IDC + JST combined, 10-pin IDC only, and JST only.

The KiCad project contains four configurations. Pick one when fabricating the PCB:

All variants share the same power-input + reverse-protection + filter section. Only the per-slot connectors differ.
