From the project

EuroRack sytle analog synthasizer designs

These are designs for EuroRack compatable synthasizer modules.

Each module is designed as a seperate project in KiCAD Each folder includes a BOM from Mouser.com, the Gerber Files if you just want to have a board printed and a PDF of the schematic.

I have taken insparation from all over the web including Music From Outer Space, Yusynth and Look Mom no Computer. Some designs are outright copies of their schematic with my board layout design.
