Wiring Diagram

There is a lot of wiring in this so it's best to take it component at a time. Also the exact pins used will depend on the exact placement of parts so keep that in mind as you are prototyping, as neater wiring helps with compact builds. We will use the extra GND and 3.3V pads on the feather's prototyping area. Additionally 3 parts will be connected to the battery directly the Feather, Audio FX board and NeoPixel Jewel. I found that it was easiest to connect all the direct battery connections using the prototype area on the Feather.

For the wiring diagram the black wires are all ground. The solid red is connections to the battery where the dashed red is connected to the regulated 3.3V.

Audio FX board

We will actually use the JST connection at the bottom of this for the battery, meaning Vin on the soundboard will need to be attached to the BAT pin on the feather.
