This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!
Click to enlarge. GEMMA's D1 pin is wired to the first pixel ring's input pin. Signal output of first ring chains to subsequent ring's input pin, and so on.
GEMMA's Vout pin is wired to all four pixel ring's VCC pins. Likewise GEMMA's ground pin is wired to all the rings' GND pins.
