A 12 V (9-14 V) four-pin SK6812: the same 5050 outline and pin positions as the 5 V part, so it is easy to mix up with one. Single data line only - there is no backup-data input, unlike the WS2815.

Outline and pin positions checked against the manufacturer datasheet (OPSCO SK6812HV sheet, same drawing as SK6812). Pin numbers follow the 2021+ OPSCO sheets (1 GND at the cut corner, 2 DIN, 3 VDD, 4 DOUT); the 2015 sheet numbers the same pads 1 VDD, 2 DOUT, 3 VSS, 4 DIN. What this means.

Compatibility

  • near clone SK6812

    The same 4-pin 5050 outline and pin positions as the 5 V SK6812, but a 9-14 V supply: plugging one into a 5 V SK6812 layout, or the reverse, destroys it or leaves it dark. Data timing windows overlap the SK6812's. source ↗
