# Hardware datasheets

Local PDF references cover all **18 SKUs / 43 placements** in the current
0.0.11-dev factory BOM, plus the host/LCD modules and historical alternatives.
`manifest.json` records original paths or public source pages and SHA-256;
`bom-coverage.json` binds the table below to the exact BOM bytes.
Some documents cover a component family; coverage is not physical qualification.
The original snapshots in `reference/pdfs/` are preserved. PDFs use Git LFS.

Run `mise run datasheets:check` to validate the collection, or
`mise run datasheets:fetch` to obtain missing current-BOM PDFs.
