The part already has a Datasheet URL set, so I won’t overwrite it; I found the official XINGLIGHT PDF as the reference for the cross-check and am now comparing pins and footprint details.
Completed the part audit and wrote the detailed findings to XL-3528RGBW-WS2812B Part Review. The Datasheet URL was already set, so I did not overwrite it; symbol pinout and footprint geometry match the datasheet, but I flagged metadata issues including the 1.8×2 mm/3720 description mismatch, missing package-case metadata, unspecified pin types, missing pin descriptions, and RGBW/temperature ambiguities.
Suggested next steps:
Update pin types/descriptions from the datasheet.
Correct the package/description metadata to SMD3528-4P, 3.50 × 2.80 × 1.85 mm.
Decide whether to replace the existing uploaded Datasheet URL with the official XINGLIGHT PDF URL.
