Investigate the scope of changes for Boron #80

Particle is discontinuing Electron 😢. We have decided to use Boron. We need to investigate what we need to change to swap the Electron Deadline: Before Particle Boron is ordered

This is actually something I came across as an issue in another project, so I figured I'd chime in here. Fwiw, Particle still supports the Electron, but supply might dwindle.

The main difference between the two is IO. The Electron is also 5V-tolerant for most of their pins, but the Boron maxes out at 3.3. As for the exact IO differences, I've copied the table below. The difference in UART IO was a huge problem for me, but it might not be in your case?
