This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!

Two NeoPixel sticks are wired in parallel to GEMMA:

  • GEMMA GND to NeoPixel sticks GND
  • GEMMA D1 to NeoPixel sticks DIN
  • GEMMA Vout to NeoPixel sticks 4-7VDC
  • 500mAh battery connected to GEMMA's JST port
  • GEMMA's on/off switch used to toggle power
