This is a minimalist holder for an Adafruit Gemma M0 and a Neopixel jewel, assembled back-to-back. I use the resulting assembly as a programmable LED candle/light source.
The Gemma is held in place by a press-fit, while the Jewel slides in under little hooks. There is a slit on the side to pass the connecting wires through, so the electronics can come out without having to desolder or otherwise disconnect the parts.
The basic sizing and press-fit mounts are reused from the Adafruit torch model.
