nRF9160 DK v0.9

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 P24.
    Removing the jumper disconnects the nRF9160 from the power management circuitries on the DK.
