Hog Moduleur / Default Patch

An optional passive PCB which connects the modules of the Shmøergh Moduleur. This essentially creates a default patch which makes the Moduleur playable without patch cables.

Module specific instructions

🐛 3D model bug in schematics

The current version of the 3D model has two bugs:

  1. It incorrectly uses dual row headers. Single row, long pin headers should be used on the BACK side of the PCB so that it can connect to the UI board through the holes on the Core board.
  2. The side of the ADSR+VCA1, ADSR+VCA2 and UTILS pin headers are wrong. All pin headers should be soldered on the BACK side of the PCB.

Questions

How big is the Default patch PCB?

It measures 210.7 × 32.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Default patch use?

30 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Default patch KiCad files?

From the shmoergh/moduleur repository on GitHub, at the commit this page was made from: the board is modules/08-default-patch/default-patch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Default patch design in my own project?

Its repository states no licence, so its author keeps all rights: ask shmoergh before reusing the design.
