ESPHome mmWave Presence Sensor Case

My ESP32 board has 30 pins and measures about 29mm x 52mm. I had to remove the pins to make the whole assembly thin. I wasn't happy with how large the other enclosures that I could find were. I also didn't find many cases that fit the LD2420 module. 

I placed the PCBs side by side so I could bridge the 3.3v and GND.

My modules had firmware 1.5.9. The case press fits, you may want/need to drill the holes to get it to fit.

Here's my yaml for configuring the board with the wiring shown (for my firmware) in the photos for anyone that wants to skip the learning stage of doing one of these.
