NeoPixel strips have 3 pads for wires. Power (+5v) and Ground (GND) can be connected from either end of the strip. The middle pin (Din or Dout) must be connected from the correct end or the pixels won't light up. Always look to be sure you're connecting to IN for your data line.

Our NeoPixel strip will connect at its IN end as follows:

  • VOUT --> 5v
  • A1 --> DIN
  • GND --> GND

The Fairy Lights strand wires are connected to pins A4 and GND on the Circuit Playground Bluefruit.
