RGBW with a backup data line, and a driver IC rather than an integrated LED - it typically drives external dies at 12-24 V. Included as the RGBW sibling of the WS2813; no single-package part is seeded for it yet.

Clones & compatibility

“Compatible” is never stated bare here — each relationship carries how strong the claim is, and what bites if you assume too much.

Parts using this protocol

No package is catalogued for this protocol yet — it is seeded for family completeness, or it is a driver IC that drives external LEDs rather than shipping as an integrated package.

Dating evidence

Evidence, not a release date. A library commit proves the part existed by that date and says nothing about how long before.
