There are three wires we need to attach: red for power, black for ground, and yellow (or sometimes white) for data.
- Red goes from VOUT to +5V
- Black goes from GND to GND
- Yellow goes from A1 to DIN
You can plug a battery pack into the battery connector, or plug into the USB port to power your project.
Note: A0 is connected to the speaker, so we suggest using the other pads that are free, like A1.
