# 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"
