Overview
Psu is an open-source printed circuit board by shmoergh, from the shmoergh/moduleur repository on GitHub. It is a 2-layer board of 250 × 32 mm with 31 parts on 36 nets, routed with 96 tracks and 1 via.
It is built around the 1.5KE36A and PB400EEQR1BLK. Its parts include 6 connectors, 5 diodes, 3 resistors, 1 IC and 1 switch. It belongs with the audio and music and power boards of this library.
Main components

modules/08-default-patch/README.mdHog 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.
How to Build
Module specific instructions
🐛 3D model bug in schematics
The current version of the 3D model has two bugs:
- 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.
- 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 Psu PCB?
It measures 250 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Psu use?
31 parts, built around the 1.5KE36A and PB400EEQR1BLK. 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 Psu KiCad files?
From the shmoergh/moduleur repository on GitHub, at the commit this page was made from: the board is modules/01-psu/electronics/psu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Psu design in my own project?
Its repository states no licence, so its author keeps all rights: ask shmoergh before reusing the design.
