Compatibility

  • protocol compatible SK6812

    Only the title (XL-2020RGBC-SK6812B) says SK6812. The sheet adds a second data input (FDIN, pins DI1/DI2) and 5 mA drive; its timing table is the same 0.25/0.47 us set as the Xinglight 1515/2020 "2812B" sheets, which has nothing in common with the OPSCO SK6812 sheet. source ↗
