Wi-Fi LED strip controller that works well

Components required for DC-DC and support of 24 volts are not delivered yet. But everything else is here and I baked first couple boards.  Blue wire is a temporary shortcut to make tests possible.

Board stays cool when loaded for 7A (85W). For brightness regulation I use LEDC peripheral of ESP32. It can handle 512 levels for smooth level changes. Base frequency is 80KHz and noise is inaudible for humans.
