Wifi controller for Neopixel SK6812

by okra63 on Thu Jul 09, 2020 11:53 pm

I'm trying to find an Alexa-compatible controller for Neopixel strips (SK6812). I have found a number of controllers (5v) that are 3 wire, that say they support SK6812. Does anyone know if the strip will function properly if I wire both ground wires from the strip to one ground on the controller?

Thanks a bunch.

If the controller is also supplying power to the strip, there is no need to connect the second ground wire. Both ground wires connect to the same place on the strip.

The the second ground wire is used when the 5v power supply is separate from the controller.
