A six-pad addressable LED with two data inputs (DI0, DI1) and two data outputs (DO0, DO1), driven by the IC the sheet calls AB1002A. The sheet is a “temporary version” release and the part is not a pin-compatible replacement for any 5050 or 2020 part: the package is 2.2 x 2.2 mm with pads on two edges, listed by LCSC as “SMD2222-6P” while the part number says 2020.

Pin order is column-wise, not a ring: the right column from the top is GND, DO1, DO0 (pins 1 to 3), the left column from the top DI1, DI0, VDD (pins 4 to 6). The catalogue’s drawing places each pad by those printed names and numbers.

What the sheet says about the two inputs is on the protocol page; it does not say which of DI0 and DI1 is primary or how the second input is used. Not verified on hardware. LCSC stock 4,320.

Outline and pin positions checked against the manufacturer datasheet (C22461777 TBA-T2020M-J1I16 spec, PDF p4 / printed p3 (front view, front see-through view, polarity diagram) and PDF p5 (pin table)). Not a ring: pins 1 to 3 run down the RIGHT column (1 GND top, 2 DO1, 3 DO0 bottom), pins 4 to 6 down the LEFT column (4 DI1 top, 5 DI0, 6 VDD bottom). The pad names are printed on the see-through view; the numbers are from the pin table. Pad size and pitch are the sheet's labels (0.55 wide, 0.35 tall, 0.30 gap, 1.1 gap between the columns). The nick mark ('A') is drawn at the bottom-right corner of the front view, beside DO0; the sheet does not say it marks pin 1. What this means.
