Eurorack Busboard

Eurorack Modular Busboard Psu Power-Supply Utility Easy-Build Through-Hole

This module is part of my Eurorack series. The busboard is connected to your power supply and can power up to 20 modules in your system!

The PCB/Kit is available in my store

Key features

  • 20x IDC 16-pin Eurorack power sockets
  • -12V, +12v and +5V rail
  • CV and GATE rail
  • LED indicator for all voltages
  • optional terminal for all signals
  • easy to build, all through hole components

How it works

The busboard distributes power to up to 20 Eurorack modules. The power supply is either connected via a 16-pin flat ribbon cable or the terminals on the board. There are three LED’s which signal the operational status of each power line.

Dimensions: 154mm x 67.5mm


Begin with the components with the lowest profile and work your way up. All components have a fixed designator and a component value printed on the board. Additional information on the parts can be found in the BOM below.
