"Neopixel-like"
not all led strips are the same..
You talk about anode/cathode but neopixels doesn't have these... (not externally anyways)
Neopixels does have a +5v and a gnd... but since they are individually addressable you need a controller to make them do anything.
How about some information on your Leds, where did you get it from, Perhaps a URL so we can find out what it is and what it requires. Or clear pictures.
