WS2812B Part Review


Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll inspect the part metadata, look for an official datasheet if needed, update the Datasheet property, then compare symbol/footprint/pins and summarize any mismatches.
I found the official Worldsemi WS2812B 5050 datasheet and added it as the part’s Datasheet URL property. I’m now checking pinout and footprint geometry against that source.

Completed the WS2812B part review and added the official Worldsemi datasheet URL: https://world-semi.com/web/userfiles/productfile/WS2812B_V5WDatasheet_V6.1_EN.pdf.
Full findings are in WS2812B Part Review. Key flags: footprint pad mapping appears to swap DOUT and GND, Manufacturer Name appears to be SparkFun instead of Worldsemi, and package/description metadata is missing.
Suggested next steps:
  1. Fix the footprint pad mapping.
  2. Update manufacturer/package/description metadata.
  3. Rename DI/DO terminals to DIN/DOUT for datasheet consistency.
