The circuit diagram above shows how the components will be wired together. This won't be 100% exact in the actual circuit but it's a very close approximation.
Solder all of the sides together except the last DIN and DOUT, leave those two last ones separated. DIN is where the data will feed into the neopixel ring.
- 5V+ Power on NeoPixel ring to BAT on Adafruit Feather.
- Ground on NeoPixel ring to GND on Adafruit Feather.
- DIN on NeoPixel ring to Pin 6 on Adafruit Feather.
