This diagram uses the original Gemma but you can also use the Gemma M0 with the exact same wiring!
Wired Connections
The circuit diagram above shows how the components will be wired together. This won't be 100% exact in the actual circuit but it's a very close approximation.
- GND on the Trinket to GND on the Jewel
- D1 on the Trinket to DIN on the Jewel
- Vout on the Trinket to PWR on the Jewel
Battery Power
The circuit will be powered by a 3.7V 150mAh Lithium ion battery via JST connection. The battery plugs into the JST slide switch adapter.
