NeoPXL8 FeatherWing for Feather M0 - 8 x DMA NeoPixels

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 3V logic input
Feather-side NeoPXL8 input logic; the Adafruit product page says the FeatherWing converts 3.3V logic level to 5V logic for the NeoPixel outputs.
Type · SignalVoltage · 3.3V logic input, source-backed product-page wording
5V logic output header pairs
2 x 8 header option for NeoPixel output connections; product page states ground and 5V-logic signal are provided in pairs.
Type · SignalVoltage · 5V logic signal, source-backed product-page wording
GND header pairs
Ground return paired with each NeoPixel signal on the optional 2 x 8 header output.
Type · GroundVoltage · 0V ground
RJ-45 signal outputs
RJ-45 Ethernet-jack option for NeoPixel output connections; product page states ground and 5V-logic signal per twisted pair, matching OctWS2811 wiring.
Type · SignalVoltage · 5V logic signal, source-backed product-page wording
RJ-45 GND pairs
Ground returns paired with each RJ-45 NeoPixel signal twisted pair.
Type · GroundVoltage · 0V ground
External NeoPixel power
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.
