Hi,
I have a NRF52840 DK , I was using it for development. After one day the board don't turn ON anymore. I'm using USB cable as a power source. Acording to several subject I tried to turn it on holding the RESET button to enter the bootloader but nothing happen.
While using the USB cable the power section start to heat a lot, especially the L80 component (4.7µH Shielded Wirewound Inductor 2.23A 201 mOhm Max Nonstandard). And the shield of this inductor is a little bit broken/rip off.
Anyway we are planning to use the waranthy but I would like to know if I did something wrong.
Best regards,
Thanks to help me
