Idea, Code and Schematic based on https://www.espthings.io/index.php/2023/09/02/esphome-panasonic-climate-interface/ and https://github.com/DomiStyle/esphome-panasonic-ac/
I have a great dislike for dupont cables, and I have a number of excess naked ESP32 wroom 32 (not dev boards). So id rather design a custom board, than rely on a devboard.
