README
README.mdEurorackModules
Open-source eurorack synthesizer modules. All our schematics and pcbs are developed with KiCad.
1U modules
These are simple (passive) utility modules, designed to fit the Intellijel 1U spec. They are often smaller (6 or 8HP) so you can use them to fill gaps in your system. Except for the Multibus... that one takes up an entire row.
| Module | Description | |
|---|---|---|
 | LPG | A simple passive low-pass gate with -6dB slope in a small 1U package. |
 | Mute | A signal mute (momentary and latching) in a convenient 1U package. |
 | Mult | Dead simple passive multi. Its only feature being very small. |
| Multibus | A eurorack module for the distribution of CV signals. |
Regular (3U) Modules
Just your regular sized eurorack modules.
| Module | Description | |
|---|---|---|
| Corona | A multi purpose vacuum tube (or valve) drive module with feedback control. |
Other stuff

Questions
How big is the Multibus frontboard PCB?
It measures 526 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Multibus frontboard use?
79 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 Multibus frontboard KiCad files?
From the coriolisinstruments/EurorackModules repository on GitHub, at the commit this page was made from: the board is Multibus/hardware/Multibus/Multibus_frontboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Multibus frontboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask coriolisinstruments before reusing the design.
