nRF9160 DK v1.0.0

Preparing the development kit for current measurements

To measure the current consumption of the System in Package (SiP), you must first prepare the Development Kit (DK).

  1. Remove jumper from P22.
    Removing the jumper disconnects the nRF9160 from the power management circuitries on the DK.
