I bought a ESP 32 board and my arduino ide(updated) is unable to detect and the board is not getting connected so how should i connect it and the board is working properly
Is the board detected by your PC when you connect it ?
It appears that board has a cp2102 usb interface chip.
Are you certain that you are using a usb cable with data lines, and not just power?
Do you have a driver for the cp2102 on your computer?
What OS, try several cables. Any LEDs lit?
Have you tried another controller since the update?
Can you please tell us the OS and IDE version?
