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. Some of the connections, such as the positive and negative pads on the bottom of the Trinket, are not visible in the diagram, so it's a good reference, but not exact. Note, the order of the connections on the push button are different than the physical one.

  • Adafruit Trinket Power to C1 on Push Button
  • Adafruit Trinket GND to GND on JST Switch
  • Adafruit Trinket GND to GND on NeoPixel Jewel
  • Adafruit Trinket BAT+ to PWR on NeoPixel Jewel
  • Adafruit Trinket #0 to Data Input on NeoPixep Jewel
  • Push Button LED + to GND on JST Switch
  • Push Button LED – to C1 on Push Button
  • JST Switch + to NO on Push Button 

Battery Power

The circuit will be powered by a 3.7V 2200mAh Lithium ion cylindrical battery via JST connection. The battery plugs directly into the Switched JST-PH 2-pin breakout board.
