Wall bracket for Sonoff NSPanel (US version)

A few months ago, i bought a Sonoff NSPanel knowing that i would be able to flash ESPHome on it. I really liked the design of the display. What i did not like though, was the screw terminals for AC input on the relay box. They are not the best quality and i don't trust them. Also, the switch i originally intended to replace controls an outlet and having only a 2 amp relay turning on an outlet is not a very good idea.

I instead designed a wall bracket for the display it modified the panel so that it could be powered from a USB cable. I designed a replacement back cover for the display which has hooks for mounting to the wall bracket.

The 8 pin header that normally connects to the relay box has pins for 5V and ground. So, I removed that header and soldered wires to a USB-C breakout board mounted on the back cover.
