Gemma Jewel circuit

The NeoPixel Jewel is beautiful. It's like a small NeoPixel ring except that it also has a NeoPixel in the centre. It's perfect for glowing jewel effects, and there are a variety of tutorials on what to do with them. But first we need to assemble the circuit, and usually into the smallest space possible. Adafruit have a lovely wiring diagram in one of their tutorials. But we want to stack the Jewel and the Gemma v2 (the on-board on/off switch is great) back to back.

So, first, solder your wires on to the NeoPixel Jewel.
