Meihua’s WS2812B-shaped 5050 pixel (5.4 x 5.0 mm, 1 VDD, 2 DOUT, 3 VSS, 4 DIN, cut corner at pin 3 - the same outline and pin order as the WS2812B-5050 here). Its driver is not named; the sheet’s tables are word for word those of the Amicc A-SC5050ARGBC-B02 sheet. Absolute maximum 3.0-7.5 V; 400 mW. LCSC stock 1,940.

Compatibility

  • electrically similar Amicc SC5050A-B02

    The Amicc A-SC5050ARGBC-B02 sheet (Feb 2023) prints the same parameter limitation, electrical, dynamic and timing tables as the Meihua sheet (June 2022) number for number, and the same 5.4 x 5.0 mm outline and pin order; neither sheet names the IC or says it is a second source. The two are kept separate because the sheets are by different companies. source ↗

  • electrically similar TZ2812

    The TUOZHAN TZ2812 sheet prints the same typical timing figures (T0H 295 / T0L 595 / T1H 595 / T1L 295 ns), 80 us reset and GRB order, and the same 5050 pin order. Window widths differ (TZ2812: T0H 200-350 ns; Meihua: 295 +/-50 ns), supply is 3.0-7.5 versus 3.5-7.5 V, and PWM is 3-5 kHz versus 4 kHz. No sheet states that one is a copy of the other. source ↗

  • electrically similar of this Amicc SC5050A-B02

    Identical tables to the Meihua MHP5050 sheet (see that protocol); neither sheet names the IC.

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.
