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.
Shield
Verify supply voltage and logic levels before powering up.
Module pins: External NeoPixel power, GND header pairs, RJ-45 GND pairs, Feather 3V logic input, 5V logic output header pairs, RJ-45 signal outputs. Schematik maps them to your board in the app.
About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.

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.
