Marketed for persistence-of-vision and high-speed video, where the APA102’s 20 kHz PWM starts to show. Its headline specifications are vendor claims rather than a verified datasheet - see DATA-QUALITY.md.
Current per channel and the maximum are left blank: no datasheet for this part is held, and the earlier 20 mA / 60 mA figures were a design rule of thumb rather than a sheet’s rating. A blank makes you check; a plausible wrong number does not. The 120 degree viewing angle and 1.7 mm height were unsourced and are blank.

Protocol — HD107S
This is an SPI part: the clock is explicit, so there is no fixed bit period. The frame layout is shown below.

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
Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
