This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!
Route your NeoPixel strip's wires through the hole at the top of the enclosure, and solder them up to GEMMA:
NeoPixel GND -> GEMMA GND
NeoPixel + -> GEMMA Vout
NeoPixel signal -> GEMMA D1
Seat GEMMA into the round outline inside the enclosure, with the USB port facing its opening at the bottom end of the enclosure.
NeoPixel GND -> GEMMA GND
NeoPixel + -> GEMMA Vout
NeoPixel signal -> GEMMA D1
Seat GEMMA into the round outline inside the enclosure, with the USB port facing its opening at the bottom end of the enclosure.
Use a JST extension and slide switch to make this tiny adapter. The slide switch fits into the opening in the enclosure and now you can easily power up your circuit while still making it easy to disconnect the battery for recharging.
