Outline and pin positions checked against the manufacturer datasheet (C54857378 XL-3535RGBC-XS2812B p11 (outline, solder pattern, labelled top view)). Counter-clockwise from the bottom-right: 1 GND (at the cut corner), 2 DI, 3 VDD, 4 DO. VDD is top-left, as on the WS2812B, but the numbering starts at GND. What this means.
