A high-refresh APA102-protocol part aimed at POV and film use. Included because it is what people reach for when the APA102’s 20 kHz is not enough, but its published specifications should be treated as marketing until someone verifies them on a scope.
Refresh & flicker
Advertised around 27 kHz, higher than the APA102’s 20 kHz, and marketed for high-speed video and persistence-of-vision work. That is a vendor figure, not verified against a datasheet this catalogue holds, so the PWM field is left blank - see DATA-QUALITY.md.

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

APA102
Driven with the APA102 protocol by every library, and generally treated as a faster APA102. The caveat is that the specifications are vendor claims rather than a verifiable manufacturer datasheet, and the HD107S, APA107 and APA102 are frequently conflated in listings.

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