user71205: I am trying to bring the esp32 example code live. I am able to upload the image error free but when I remove the jumper and then press the reset switch, instead of seeing it logon to my network via serial monitor, I just get this repeating over and over and over again.

user69592: The message:

Brownout detector was triggered

is being generated by your ESP32 because there is a problem with the Vcc power to the module.
Check the following:

Your USB cable.  Some cables are just plain cheap and can't supply the power the ESP32 needs.  Get a better one.

Some PCs are not able to supply enough power from their USB ports to supply the ESP32, try a powered USB hub and/or a different PC.

Some ESP32 modules are poorly made and may have bad solder joints or low quality components.  Your only real option here is to buy a better ESP32.

If you are powering other components from the ESP32's power supply, stop it.  Power any accessories separately.
