Docs site: https://tyevco.github.io/prettycoolboards/

Open hardware boards designed as code. The schematics and PCBs are generated from Python into KiCad 9, routed with Freerouting plus a grid router, and gated by ERC, DRC and schematic parity before any fab output is written. Enclosures and mechanics are in build123d.

Repository layout

tools/        shared Python → KiCad generator toolchain (see tools/README.md)
caliper/      one folder per board: hardware/, firmware/, app/, docs/
.vitepress/   docs site (VitePress), published to GitHub Pages by .github/workflows/docs.yml

The hardware toolchain runs on Linux: KiCad 9 (kicad-cli + pcbnew), Java 21 + Freerouting 2.1, ngspice and build123d. On Windows, run it in WSL.
