Re: esp32 seems dead

It is critically important that one observes the current limitations of the output pins and always utilize a current limiting resistor. The ESP32 sink/source current is referenced to +3.3V and not to +5V, so if you are sinking current (output port goes low) and the LED is at +5 Volts, this is not a ...
