# PCB Layout

For connecting [Waveshare 2.9inch Touch e-Paper HAT](https://www.waveshare.com/2.9inch-Touch-e-Paper-HAT.htm) with an ESP32

## Controller Selection

12E/12F style module for simplicity, and ICSP with an external serial TTL.

Will probably be worth running a paste stencil.

## Enclosure Considerations

Intent is for this to fit into a junction box, so it can mount to a printed 
replacement for a switch plate.

NA Jbox screw spacing: 

* "Box Mount" (Where the switch mounts to the jbox): 3.281"
* "Strap Mount" (Where the cover plate mounts to the switch): 3.812"
