There are a lot of pieces to this project, but many of them just plug into one another so it's not quite as complex as it seems. 

NeoPixel Wiring: 

• +5v to USB Breakout VCC
• G to USB Breakout G
• DI to Qt Py A1 (aka pin 25)
• G to QT Py - (G) pad on the back of the USB port

PDM Microphone Wiring:

• Plug into the QT Py Stemma Port with a Stemma connector. Yellow wire will be connected to GPIO 19 and blue wire will be connected to GPIO 22.

Momentary Switch Wiring:

• One leg to A3 (aka GPIO 15)
• Other leg to QT Py G pin

Power Wiring:

• USB battery plugs into the power switch tail
• Power switch tail plugs into the USB C male-male adapter
• USB c adatpter plugs into the "power" input to the USB splitter (with the lightning bolt)
• USB splitter male connector plugs into the QT Py
• USB splitter female (headphone) connector plugs into the USB breakout/NeoPixels

This is a little bit convoluted, but it gets things done without having to build custom USB cables, and there's plenty of room in the top hat for a few extra adapters.
