I have been working on this project for about a year at this point, and from my first PCB iteration to now I think I have finally finalized what I want this project to be about.

Implemented Functionality:

Battery Back-Up for Photon's internal RTC

4 Relays for Controlling 4 AC outlets

4 USB-A ports for powering additional Photons doing awesome things

Barrel Jack Input for variable power 5V supplies for High or Low current downstream applications

Basically final schematic

First Layout
