We'll use the headers that come soldered to the assembled PropMaker Wing to mount it directly on top of the Feather M4 Express, to make the smallest possible package to hide inside the staff.
The on/off switch will be soldered into the GND and ENABLE pins near the reset button on the PropMaker Wing.
The speaker, battery, and NeoPixel ring will plug into their respective ports on the PropMaker Wing using JST connectors.
The NeoPixel ring will be soldered to the 3-pin JST connector as follows:
- Red wire --> PWR
- Black wire --> GND
- White wire --> IN
We'll also connect the NeoPixel ring to the NeoPixel strip as follows:
- PWR --> 5V+
- GND --> GND
- OUT --> IN
