## What this site is

SeriousParts is a parts ledger, not a checkout cart. Each part page records identity (name, MPN, SKU, category), vendor, attributes, documents such as datasheets, prices when known, and a source URL back to the original listing.

## Sources currently in the catalog

- LCSC Electronics
- Adafruit
- SparkFun
- Sears PartsDirect

## How to cite a part

Part URLs follow `https://seriousparts.com/parts/{id}`. Prefer the MPN plus the canonical SeriousParts URL. Vendor pages live at `https://seriousparts.com/vendors/{id}`.
