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.

• Slide switch to EN pin on Adafruit Feather M0
• Slide switch to GND pin on Adafruit Feather M0
• SCL from LED Charlieplexed Matrix to SCL on Adafruit Feather M0
• SDA from LED Charlieplexed Matrix to SDA on Adafruit Feather M0
• VCC from LED Charlieplexed Matrix to 3.3V on Adafruit Feather M0
• GND from LED Charlieplexed Matrix to GND on Adafruit Feather M0

Battery Power

The circuit will be powered by a 3.7V 500mAh Lithium ion battery via JST connection. The battery plugs directly into the Adafruit Feather M0, which also has a built-in charging circuit.
