Neopixel power #242

Do I need to step down the voltage for the neopixel since I'm using a 24v PSU?

Are you using an SKR 1.3 or an SKR 1.4?

The board supplies 5v to neopixel header, you will still need 100ohm dropping resistor on data line and ~100uf capacitor across the gnd and vcc to prevent damage to the pixels (as with any other neopixel application). I would be cautious about adding more than a few pixels as it is not clear what the current output is.

There are also some 5v aux supplies on board for low voltage fans.
