Since we first started carrying NeoPixels back in 2012, the chainable RGB LEDs have taken over the world. And a big part of that success is due to the simplicity of their wiring - just one data wire, no matter how many pixels you've got.

Feather-side NeoPXL8 input logic; the Adafruit product page says the FeatherWing converts 3.3V logic level to 5V logic for the NeoPixel outputs.
2 x 8 header option for NeoPixel output connections; product page states ground and 5V-logic signal are provided in pairs.
Ground return paired with each NeoPixel signal on the optional 2 x 8 header output.
RJ-45 Ethernet-jack option for NeoPixel output connections; product page states ground and 5V-logic signal per twisted pair, matching OctWS2811 wiring.
Ground returns paired with each RJ-45 NeoPixel signal twisted pair.
External power feed for the NeoPixel strands; product page says many amps are needed and recommends terminal blocks or bus bars instead of routing that power through the FeatherWing.
