My esp32 getting very hot and I can't upload the code anymore

Postby Ahmed hani » Wed May 10, 2023 12:45 pm

Hello
I had a project controlling RGB strip 12v with my esp32 so I used 7805 to regulate the voltage to it and npn transistor 2n2222a to take 3.3 pwm and convert it into 12 pwm the circuit was running perfectly until I noticed that 7805 was getting very hot the the esp32 led brightness is getting lower and lower then the esp32 get also very hot so I plugged it out and try to use it by USB in my laptop but also getting hot and I can't upload the code anymore I measured the output of 3.3 regulator on esp it was 3.3v so what is the problem and how to solve it

Sounds like something catastrophic happened (12V or 5V directly to the ESP32 GPIO pins, possibly via a transistor that has one pin accidentally disconnected or something?) and your ESP32 is fried.
