The Concept

Greenface Labs designs and builds open-source Eurorack Synthesizer Modules

More and more people are embracing the rapidly growing DIY synthesizer movement. Greenface Labs was created to support this community by sharing useful and unique designs in the public domain.

Design files are free on GitHub

Greenface Labs provides the schematics, bill of materials (BOM) and Gerber files that can be used to manufacture the boards. Each product page contains a link to the Git archives for that product. See the products

There are 2 ways to get kits*

  • Do it your way
    • Get the design files on GitHub
    • Use the Gerber files to manufacture the boards
    • Use the component position file to place the parts for assembly
    • Use the BOM files to specify and purchase parts
    • Assemble all remaining parts.
  • Have Greenface Labs handle everything for you
    • You just have to wait for the boards to be delivered
    • Then do the final assembly adding jacks, LEDs, etc.

Board fabrication and assembly services are provided by JLCPCB.

* Kits typically consist of a panel and a board with SMT components installed. The customer is responsible for getting the remaining parts (usually jacks, buttons LEDs, etc.) and the shipping costs associated with JLCPCB.

Originally founded in 1975, Greenface Labs was put on hold when founder Shannon Vance got a job in the space industry and then later designing DSP-based telecom test equipment. Now mostly retired, Shannon has resurrected Greenface Labs to fulfill his vision from long ago.
