either type.

All individual NeoPixels can be chained from a

single microcontroller pin, with the one caveat that

WS2812 and WS2811 (e.g. Flora V2 and V1) types

can’t be mixed in a single chain.

Each individual NeoPixel requires 60 milliamps max

at full brightness. Mixed colors and lower

brightness settings will use proportionally less

power.
