Meihua’s 1.5 mm pixel with an unnamed driver (the “IC” in the part number). Pin order is not the same as any 1.5 mm part from OPSCO or TUOZHAN in this catalogue: 1 GND, 2 DO, 3 VDD, 4 DI, running clockwise, with pin 1 at the green corner square bottom-left. The sheet’s wording “IC compatible, easy assembly” is in the features list and is not explained.

Datasheets disagree with themselves: the electrical table header says VDD 3.0-5.5 V and the supply row 3.5-5.5 V (see the protocol page); the sheet lists a “W” luminous-intensity row (and bins T1, U1, U2 for it) although the part has red, green and blue emitters only. LCSC stock 8,120.

Outline and pin positions checked against the manufacturer datasheet (C3028831 MHP1515ICRGBDT Rev.1 p2 (package dimensions, top and bottom view, recommended solder pad) and p3 (pin diagram)). Top view: 1 GND bottom-left (green square), 2 DO top-left, 3 VDD top-right, 4 DI bottom-right - clockwise from the bottom-left. Bottom-view pads are 0.5 mm with a 0.5 mm cross gap; the recommended solder pad drawing beside it is larger. Approximate. What this means.

Compatibility

  • electrically similar SK6805

    Inferred from the numbers only; the Meihua sheet never names OPSCO or any other IC. Its T0H 300 / T0L 900 / T1H 900 / T1L 300 ns (+/-50 ns) match the typical values OPSCO prints for the SK6805-EC15 (T0H 300, T0L 900, T1H 900, T1L 300), and Meihua resets after 200 us like the SK6805 sheet. But the pin numbering differs (Meihua 1 GND, 2 DO, 3 VDD, 4 DI; SK6805-EC15 1 DIN, 2 VDD, 3 DOUT, 4 GND), colour order is RGB here where OPSCO's SK6805 sends GRB, and the +/-50 ns tolerances are tighter than OPSCO's windows. Not tested. source ↗

  • electrically similar of this Nationstar FC-RGBC4020 IC (unnamed)

    Same typical timing (300 / 900 / 900 / 300 ns +/-50 ns) and reset above 200 us as the Meihua MHP1515 sheet; Nationstar sends GRB where Meihua says RGB. Neither sheet names an IC or says one is derived from the other.

Dating evidence

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
