Have I damaged my nRF52832 Dev Kit?

Rick

I have been analyzing the current consumption of my nRF52832 dev kit today using both a multi meter and an oscilloscope with a resistor. I'm not sure what I exactly did that lead to this, but now my board constantly uses 80mA. It can still be programmed and it does seem to run. Did my board get damaged somehow? If so, can it still be fixed?

Edit: What could have happened is that the dev kit was powered for a short time without a jumper on P22 (also no short on SB9 nor resistor on R6). Not sure what this could do to the board.

Edit2: The issue was temporarily fixed by replace the nRF52832 chip on the dev board but now it's back again. Not sure what I'm doing wrong.

    No, the dev kits are not very sensitive to ESD. Have you shorted SB10 or SB11? Are you measuring on P22? Do you have a resistor on R6?

    Is the chip still functional?

    If you test with some of the BLE examples in the SDK, is the BLE still working ? are you able to connect to the nRF with a smartphone?
