Outline and pin positions checked against the manufacturer datasheet (C5349953 XL-1010RGBC-WS2812B p11 (outline, solder pattern, labelled top view with pin circles)). Pin circles on the top view run in rows, not around the ring: 1 DOUT top-left, 2 VDD top-right, 3 GND bottom-left, 4 DI bottom-right. A green mark sits at the bottom-left corner (next to pin 3). Corner pads, 0.35 mm square; the mark is not at pin 1. What this means.

Compatibility

  • protocol compatible WS2812B

    Only the title says WS2812B. Its table matches the SK6805 sheet pattern (300/900/900/300 ns, 1.2 us cycle, reset over 200 us) more than the WS2812B sheet; 5 mA per channel. source ↗

Dating evidence

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
