# Datasheet Lookup

Get authoritative information for a part.

## Inputs

Either a single part query (e.g. "BME280") or a project slug (process all parts in `bom.json`).

## Method

1. Identify the manufacturer. For modules (e.g. ESP32-WROOM-32) the module datasheet is usually most useful; for ICs go to the chip vendor.
2. Fetch the official datasheet PDF when possible. Prefer manufacturer domains; avoid uncurated PDF mirrors.
3. Extract and summarise:
   - Pinout (with function per pin).
   - Operating voltage and current draw (typ/max).
   - Communication interface(s) and default address(es) for I2C parts.
   - Logic-level compatibility (3.3V / 5V tolerant?).
   - Notable quirks — required pull-ups, decoupling caps, boot-strap pins, reset behaviour.

## Output

Write to `<projects_dir>/<slug>/datasheets/<part>.md` (create the directory if absent):

- Source URL.
- Date fetched.
- Extracted summary in the structure above.
- A "watch out for" section listing the quirks — this feeds `compatibility-check` and `generate-wiring-diagram-spec`.

Cache the PDF itself under `$CLAUDE_USER_DATA/hardware-spec-assembly/cache/datasheets/<part>.pdf` to avoid refetching.
