Compatibility

  • protocol compatible WS2812B

    Only the sheet title (XL-3528RGBC-WS2812B, "WS2812B functional characteristics") claims it. The windows (0 code high up to 0.47 us, 1 code high from 0.58 us) bracket the WorldSemi WS2812B values (0.4 / 0.8 us), the symmetric typical column does not. source ↗
