Circuit diagrams and firmware source code for Gboard DIY keyboards

Open the appropriate .kicadpro file in KiCad; .pro entries are legacy projects. Keep schematics, boards, local libraries, library tables, and supporting files together.
Phys3960 is an open-source printed circuit board by Momozavur, from the Momozavur/phys3960 repository on GitHub. It is a 2-layer board of 101.6 × 50.8 mm with 15 parts on 8 nets, routed with 31 tracks and 7 vias.
KiCad design files for phys3960.
Open the appropriate .kicad_pro file in KiCad; .pro entries are legacy projects. Keep schematics, boards, local libraries, library tables, and supporting files together. Hierarchical schematic sheets are part of their parent design.
Automatic backups, recovery files, editor state, and filesystem metadata are ignored. Existing fabrication outputs and local component libraries are retained. For existing repositories, ignore rules do not automatically untrack previously committed files.
Review and save a meaningful design revision with:
git status --short
git diff
git add -- <changed-files>
git commit -m "Describe the design change"Add a clear 3D board view at docs/images/board-3d.png and, optionally, a PCB layout view at docs/images/pcb-layout.png. A schematic PDF is useful for reading circuit details. Once present, embed an image in this README with . For folders with several designs, use a separate named image for each.
Describe purpose, power and connectors, revision status, assembly requirements, and what has been physically tested. The repository setup does not establish electrical correctness or manufacturing readiness.

It measures 101.6 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
15 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.
From the Momozavur/phys3960 repository on GitHub, at the commit this page was made from: the board is phys3960.kicad_pcb and its schematic phys3960.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Momozavur before reusing the design.
