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
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.
