Then I am sorry to say that you probably damaged your chip internally by exceeding the maximum input voltage specified in the nRF52832 product specification to be 3.9V.

Thanks for the answer.

Tested with a power supply for battery voltage testing.

And all other functions are well done such as battery service, GPIOTE ,Advertising and so on.

BUT I'm sorry to say that I tested up to 4.1 V.

So nothing was done to the board between getting 0V and an output voltage from this pin? Can you confirm whether or not you made any changes to the code programmed on your chip, and/or powered it with more than 3.9V.

Best regards,

I did not connect anything on the board.

but

this is ADC value.

I do not know why suddenly this is happening.

Yesterday, the value was normally 0 ~ -2.

Did the ADC pin die?
