NeoPixel (PL9823)

Voltage Regulator

Badge Assembly

The capacitors and resistor do not have a polarity, so it doesn’t matter which way they are installed. The NeoPixel legs are a little hard to get through the solder pads, but just wiggling the LED will get them in.

Arrange the components as shown above, solder all connections in back. The attiny85 has a small dot in one corner, ensure that corner is at the top left. Solder the battery pack wires to + and -. The pixels should all light up with the predefined patterns.
