power power meter V2

 
Overview

It is stitched together with reference to multiple power meters in the site. It uses ESP32 and can communicate with WiFi & Bluetooth.
I made the board using 6 layers, and the 4th layer was modified from 6 layers. I only modified 1 internal electrical layer and added 2 GND vias, which should be fine, but I didn’t actually make the board.
Based on other power meters, OTA, MQTT, BTHome Bluetooth and
other functions have been added. Other functions are normal. The PD chip has not arrived yet. Verify the PD function after it arrives.
