The Trace Catalog
33,628 components.
Symbol, footprint, 3D model.
Every part here is a schematic symbol joined to its recommended footprint and its 3D package model — not three libraries you have to reconcile yourself. 18,712 of those links are confirmed against the footprint's own pads, pin by pin. Alongside them: 20,610 reference schematics and 34,571 routed board layouts, drawn in the browser, that the agent reads as design context.
What the catalog contains
Every artifact, gated
52,291 artifacts through a named-check gate
“Vetted” here means something specific and auditable: a parser, not a text scan, and a list of named checks recorded against every part. 781 artifacts were rejected — a symbol that reuses a pin number inside one unit, a footprint whose pads escape its courtyard, a 3D model whose scale disagrees with the footprint claiming it. Each rejection is a real upstream defect, enumerated in the build report, not a rounding error.

Reference designs
Real open-hardware designs
Schematics and routed boards from open-hardware repositories, most collected by the open-schematics dataset, with the licence, source repository and commit recorded against every one — and every one drawn in the browser when you open it. The agent reads these as context, so a schematic it draws resembles real ones.
