# RP2040 Breakout — KiCad Bridge Pipeline Demo

This board was produced **end-to-end by the Adom KiCad bridge molecule pipeline**, driven by an AI agent with no manual CAD steps:

1. **`kicad_export_molecule`** (bridge v0.9.61, one call on the AdomGPU Windows VM): exported the board STEP, ray-traced the **silkscreen top/bottom renders** (`kicad-cli pcb render`, hardware GPU), and located the sibling schematic/project files.
2. **`step2glb`** converted the STEP to the color-preserving **3d.glb** on this page (OCCT XCAF — greens/golds/blacks survive).
3. **`adom-molecule`** imported the set (GLB + pcb + sch + pro) into the Hydrogen molecule system with Blender optimization.

## Files

- **3d.glb** — full 3D model from the pipeline (open in any glTF viewer)
- **pcb.png** — the bridge's ray-traced top render (annotated silks: U1, C1–C5, Y1, J1)
- **pcb.svg** — flat copper/silk plot (kicad-cli via service-kicad)
- **schematic.svg** — the RP2040 breakout schematic
- **rp2040-breakout-silk-bottom.png** — bottom-side render
