Circuit Diagram

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

GEMMA is powered through its JST port by a 2xCR2032 battery holder with on/off switch.

Five FLORA NeoPixels are chained in the constellation of Cassiopeia to GEMMAs Vout, D1~, and GND pads with thin wire as shown above.
