KV Boards · Open Hardware Catalog

PCBs as code.
Spec → board.

Every project is a single TOML file. Placement, routing, schematics, BOM, 3D renders, and the page you're reading are all generated from it by the same Rust pipeline. Six boards live so far.

How this site works

01 — Author

One TOML per project

site/src/projects/<slug>.toml defines name, spec, BOM, schematics, mech, instructions.

02 — Generate

Rust placer/router runs it

designgraph + analytical placer + 3D VG router turn TOML into a routed .kicad_pcb. KiCad CLI exports PNGs, SVGs, GLB.

03 — Render

This site picks it up

Astro reads the TOML + render artifacts and templates each project page consistently.
