FastLED WLED Adafruit

A 5 mm through-hole addressable LED and the main alternative to the APA106. Two things catch people out: the colour order is RGB rather than the WS2812 family’s GRB, and the bit period is longer, which is why FastLED carries it as its own chipset rather than aliasing it to WS2812.

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 30 / 120 degree viewing angles on the variants were conventional figures for 5 mm domes, not from a sheet, and are blank.

Compatibility

  • 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

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.
