A gull-wing-lead pixel on the 3.2 x 2.8 mm body of the SK6812MINI-E class with leads 5.8 mm apart; named “6028” by Guiguang after its 6.0 mm text figure. Pin 1 is VDD at the top-left, not the cut lead (the cut lead is GND, pin 3).

Datasheets disagree: the text says package 6.0 x 2.8 x 1.8 mm and the drawing says 5.800 across the leads. The chip supply range is 3.5-5.5 V here. The -W sheet is identical to the -T one apart from the lens description. LCSC stock: -T 6,445, -W 22,900.

Numbers printed on the bottom view; top view: 1 VDD top-left, 2 DOUT bottom-left, 3 GND bottom-right (cut lead), 4 DIN top-right. Lead length 1.34 mm and width 0.6 mm are the sheet's bottom-view labels; the vertical lead pitch is approximate. What this means.

Compatibility

  • electrically similar SK6812

    Inferred from the printed numbers only; no Guiguang sheet names SK6812 or any IC. The 2015 OPSCO SK6812 table (T0H 300, T0L 900, T1H 600, T1L 600 ns +/-150) sits inside all four GL01H windows, as does the 5050 pin order. But the GL sheets send RGB (SK6812: GRB), reset after 180 us (SK6812: 80 us in 2015, above 200 us in 2025) and a 4.5-5.5 V supply. A GRB controller will swap red and green. source ↗

  • electrically similar Guiguang GL2121 (unnamed IC)

    The GL2121 sheet prints a different timing table (T0H 250 typ / 300 max, T0L 1000 typ, T1H 620-1000, T1L 400 typ ns, reset 80 us) and a 3.5-5.5 V supply; see that protocol. source ↗

  • electrically similar of this Guiguang GL2121 (unnamed IC)

    Same maker, same RGB order and 800 kHz rate, but a different timing table from the 5050 / 3528 / 6028 sheets (T1H 850 against 600 ns typical, T0L 1000 against 900, reset 80 against 180 us) and a lower-voltage supply range.
