This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!
LED Strip:
- Gemma Vout -> +5v
- Gemma D1 -> DI (or DIN on some strips)
- Gemma GND -> GND
Membrane LED Keypad:
- Gemma GND -> Center pin
- Gemma D2 -> Left pin
Note: some generations of NeoPixel strip have their 5V/GND/DI pins in a different order. ALWAYS USE THE PIN LABELS PRINTED ON THE STRIP, don’t just blindly follow the physical order shown in the wiring diagram!
