ESP32 Failed

I got an error:“a fatal error occurred failed to connect to esp32 timed out waiting for packet header”. I have no red light on my esp32 like I had before. Can someone help me?

What board are you using and how it is connected to your PC?


I’m using this development board:

micro usb cable is used to connect it to the PCB

I am familiar with that board, and it can have issues with low current provided by USB port on your PC. Also if you were drawing a lot of current for longer period of time, or used 5V sensor it can happen that ESP32 is burned or that onboard voltage regulator stopped working.

This board’s cheap, and have incompatible Windows 10 drivers
