Skill

datasheet-lookup

Fetch and summarise the datasheet for a part (or all parts in a project's BOM). Pulls the official PDF when locatable, extracts pinout, electrical characteristics, and typical application notes, and writes a per-part reference into the project directory.

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

Identify the manufacturer. For modules (e.g. ESP32-WROOM-32) the module datasheet is usually most useful; for ICs go to the chip vendor.

Fetch the official datasheet PDF when possible. Prefer manufacturer domains; avoid uncurated PDF mirrors.

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.
