GEMMA + 2x NeoPixel 12 Ring
In this circuit diagram, two 12 NeoPixel Rings are wired to the GEMMA. The first NeoPixel Ring has the IN pin wired to the D0 pin on the GEMMA. The second NeoPixel ring IN pin is chained to the first NeoPixel ring OUT. Both rings will share PWR and GND pins.TRINKET + NeoPixel Strip
In this circuit diagram, you will need to solder a JST female connector to the bottom of the Trinket where the postive+ and negative- terminals are exposed.
The NeoPixel Strip IN pin is wired to D0 on Trinket. +5V pin on NeoPixel Strip is wired to 3V/5V pin on Trinket. The GND pin on the strip is wired to GND pin on Trinket.
Note that the pin orders may be different than the diagram, so check the strip markings!!!
