[CLOSED]"Brownout detector was triggered" failure on my ESP32

Hello,
I tried to upload my code, everything worked but when I opened the Serial Monitor, it showed me that Issue:

PS: I tried to search a topic, but I just got a blank page so I started a new topic.

Your USB port is not providing enough power. Try another port, or else you will need an external power source (perhaps a powered USB hub).

Also, suspect your USB cable. There are some with extremely thin conductors out there.

Sorry for the whole topic, just realized I had got the wrong Uploadspeed (921600) .
Changed it to 115200 and everything is working

Hi Python Schlange,

Upload speed should not be the issue. This message is reported when voltage supplied to the chip gets too low. A spike below the brownout voltage (I believe default is 2.44 V) is enough to trigger this error. If you see this message again try replacing power supply, USB cable, install capacitor on power supply terminals of your module, etc.

Also refer to https://github.com/nkolban/esp32-snippets/issues/168 for related discussion.

Im having the same issue, Does this problem impact NVS storage?
