I have an old wemos ESP32 board that for some reason, the CP2102 IC heats up if connected to a USB charger, but works fine when connected to a PC. Probably some design flaw? Also that specific board is no longer available so if you 3D print an enclosure or make your PCB around it, it becomes useless. Compare that with boards from nRF or ST or Pico which will be available for a minimum of 10 years. Pico W is the same price as a ESP32 board.
