Why powering through Vdd pin in nRF52832 board to LiS3DH Sensor gives minimum current consumption than powering through GPIO pin?

Hi @RRain.1​ ,

you should check whether the GPIO pin of the nRF52832 has a resistance towards GND: in this case, you have to take into account this extra consumption, that might not be there in the Vdd pin case. You should also check the default status of the GPIO itself, and which pin you are supplying the VddIO (should be the same than the Vdd one).
