Manufacturer is recorded as unknown. It was previously attributed to APA Electronic here, but no source could be found that actually establishes who makes it - it is sold widely under the bare part number with no identifiable die maker. An unattributed part is better than a wrong attribution.
A through-hole 5 mm addressable LED, the main alternative to the APA106. Distinct enough from the WS2812B in both timing and colour order that FastLED gives it its own chipset entry.
Timing
| Source | T0H | T0L | T1H | T1L | Period | Rate | Reset | ± |
|---|---|---|---|---|---|---|---|---|
| fastled ↗ | 350 ns | 1360 ns | 1360 ns | 350 ns | 1710 ns | 585 kHz | 0 µs | — |
| A 1710 ns bit period, noticeably slower than the WS2812B’s 1250 ns. FastLED’s 0 us reset means “unspecified in the driver”, not “none needed”. | ||||||||
Clones & compatibility
“Compatible” is never stated bare here — each relationship carries how strong the claim is, and what bites if you assume too much.

electrically similar
WS2812B
Often sold interchangeably with the APA106 as a through-hole "NeoPixel", but the bit period differs from the WS2812B and the colour order is typically RGB rather than GRB. FastLED carries it as its own chipset for that reason. source ↗

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