Outline and pin positions checked against the manufacturer datasheet (C51900948 XL-3535RGBWC-WS2812B p11 (outline, solder pattern) and pin table). The drawing carries no pin labels or numbers; the six pads and the cut corner (top-left) are read from the drawing and the numbering is ASSUMED to run counter-clockwise from the cut corner as on the other Xinglight sheets. The drawing is 3.8 mm across including pads (body 3.5); lens split into a larger and a smaller window. What this means.
