Re: ESP32wroom ADC Failure in Current and Voltage Detection
ADC Max is Vref, which is 3.3v. You may be destroying the ADC after stressing it for a while (or just once, if the voltage fed to it doesn't exceed 3.3v then, all of a sudden, exceeds it. At least hang a 3.3v zener (and resistor, if you don't want to lose the diode) on the input. (You have no place ...
