Wired Connections

The Feather M4 Express is installed on top of the Proto FeatherWing using Headers. The NeoMatrix is wired to the Proto FeatherWing so that the Feather can be easily swapped.

5V from NeoMatrix to 3V on Proto FeatherWing
GND from NeoMatrix to GND on Proto FeatherWing
DIN from NeoMatrix to Pin #6 on Proto FeatherWing
Switch to EN and GND on Proto FeatherWing

Powering

The Adafruit board can be powered via USB or JST using a 3.7v lipo battery. In this project, a 1200mAh lipo battery is used. The lipo battery is rechargeable via the USB port on the board. The switch is wired to the enable and ground pins on the board.
