We're using four pieces of NeoPixel strip total, wired in sequence to fit neatly around the body and neck of the ukulele. The pixels plug into the NeoPixel port on the PropMaker Wing.
The battery plugs into the battery port on the Feather, and our on/off switch will be soldered into the G and EN ports on the PropMaker Wing.
Finally, the PropMaker Wing and Feather will be stacked and soldered together using the pre-soldered headers, in a nice tidy package.
We'll also wire up a custom USB port extension (not shown).
