Needs bits at least 1.75 us long, so it will not run on a WS2812B-rate (1.25 us) data stream; read the protocol page before mixing it with other pixels.

Compatibility

  • protocol compatible WS2812B

    Only the title says WS2812B-T. Its low times (T0L at least 1.55 us, T1L at least 1.1 us) make a bit at least 1.75 us long, over twice the WS2812B 1.25 us; a controller sending WS2812B-speed bits does not meet the table. source ↗
