## Files

- `bmi270-molecule.glb` — anchored OCCT molecule model (gold machine pins, Z-up, front-left pin at origin)
- `BMI270_Molecule.step` — STEP export with all 3D models substituted
- `BMI270_Molecule.kicad_pcb` / `.kicad_sch` / `.kicad_pro` — KiCad source
- `bmi270-molecule_footprint.json` — per-pad wire-attach Z
- `bmi270-molecule_symbol.json` — generated symbol

## Provenance

Exported from KiCad 10 (`kicad-cli pcb export step --subst-models`), converted
through the OCCT molecule pipeline (`step2glb --board --pin medium`) with the
publish gates green: `molecule_anchored: true`, `footprint_applied: true`,
`contact_z: 2.8 mm`, no warnings.
