Outline and pin positions checked against the manufacturer datasheet (C49237873 XL-3227RGBC-WS2812B p11 (outline and labelled top view)). The sheet has NO pin table and prints no pin numbers. Labelled top view: GND top-left, DO top-right, DIN bottom-left, VDD bottom-right; the numbers here are a catalogue convention (counter-clockwise from the green-marked GND corner), not the sheet's. Half-moon pads on the 2.7 mm edges; sizes estimated from the drawing. 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 ↗
