I just found some notes from the dawn of OS3.x and they say
WS281XBladePtr<70, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >()
- this is used ONLY for Proffieboard v2.2
WS2811BladePtr<70, WS2811_800kHz | WS2811_GRB>(),
- this is ONLY for Proffieboard v1.5"
Is that true? I thought the newer definition was just…newer.
