A gull-wing-lead pixel with the 3.2 x 2.8 mm outline, 5.88 mm lead span and pin order (1 GND, 2 DIN, 3 VDD, 4 DOUT, cut lead at pin 1) of the OPSCO SK6812MINI-E in this catalogue, so the footprints match; the TONYU sheet itself never names OPSCO. Sold and drawn by TONYU as “3528”.

Datasheets disagree: the title and LCSC call it 3528 and the part code reads S352818 (3.5 x 2.8 x 1.8), but the drawing is 3.2 x 2.8 x 1.78 mm. The drawing is used for the dimensions and the package is filed as 3228 like the MINI-E. The pin table has no numbers; they come from the drawing. LCSC stock 2,580.

Compatibility

  • electrically similar TONYU 6812F

    The 2024 TR2 sheet is a newer, different table from the 2019-era 6812F sheet: reset above 200 us (6812F: above 80 us), T1H 600/670/1000 ns (580/640/1000), PWM 1.0 kHz (1.2), quiescent 0.6 mA (1 mA), and logic thresholds of 2.8 / 1.8 V absolute rather than 0.7 / 0.3 x VDD. source ↗

  • electrically similar SK6812

    Inferred from the part code and printed numbers only; the TONYU sheet never names OPSCO or SK6812. Windows (T0H 200-400, T0L at least 800, T1H 600-1000, T1L at least 200 ns, reset above 200 us, 12 mA typical, 1.0 kHz PWM, 24 bits GRB) line up closely with OPSCO's current SK6812 sheet, and the package is the same 3.2 x 2.8 mm gull-wing outline and pin order as the SK6812MINI-E. Not tested on hardware. source ↗
