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.

    Have you shorted solder bridge SB12? Note that while SB12 is shorted, the dev kit must not be powered from USB if there is a battery or external supply connected because the protection diode has been bypassed. Also note that the allowed voltage level on external supply pins are 1.7 V - 3.6 V.
