PCBs
All circuit boards are available for free use under the MIT License. If you use them directly without significant modifications, I would simply ask that you leave the name of the organization (Lichtwerkstatt) and the designer (Canan Gallitschke) on the circuit boards.
A collection of all our self-designed PCBs. Included for each PCB are:
- KiCad files
- SVG graphics
- Gerber files for JLCPCB
The “footprints” folder contains all custom footprints.
The Excel file “Teileliste.xls” contains a list of the required components and purchase links for most PCBs.
For each board, there is a “production” folder containing a ZIP file with the Gerber files. This ZIP file can be uploaded directly to JLCPCB for production.

Questions
How big is the Einhhorn PCB?
It measures 110 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Einhhorn use?
25 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 Einhhorn KiCad files?
From the Lichtwerkstatt/ElectronicTinkerStuff repository on GitHub, at the commit this page was made from: the board is Einhorn/Einhhorn/Einhhorn.kicad_pcb and its schematic Alpaka/Fancy_Alpaca/Fancy_Alpaca.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Einhhorn design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
