From the project

The circuitboard and schematics for the Slab Keyboard system.

The full PCB, schematics, and gerber downloads for the Slab keyboard project.

- The layer User.3 stores non-polygon versions of the silkscreen text elements that can be edited. - The layer User.6 stores a printable outline of keyswitch locations, so a keymap can be drawn on paper to test the layout.

This project uses Nix for CI/CD only, to generate gerber files using KiCAD's CLI.
