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

The 3-pin JST socket cable will be soldered to the Feather.

Cut the three wires from the cable so they're about 2in (50mm) in length.
