Remove the stock cable from the pads of the first NeoPixel LED.
Remove the silicone sheathing from the NeoPixel strip section.
The 3-pin STEMMA JST cable is used to connect the NeoPixel strip to the Feather.
Use the silicone cover ribbon cable to extend the length of wire so the cable is 10in(254mm) long.
Connect Cable to NeoPixel
Solder the three wires from the STEMMA JST cable to the pads on the first NeoPixel LED.
Red wire to 5V pad, black wire to GND pad and white wire to the DATA IN pad.
Wired NeoPixel Strip
Double check the wires are properly soldered to the pads on the first NeoPixel LED.
NeoPixel Cable for Feather
