nRF9160 DK v0.8.5

Preparing the development kit for current measurements

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

  1. Cut solder bridge SB43.
    This cut disconnects the nRF9160 from the power management circuitries on the board.

  2. To restore normal kit functionality after measurement, short SB43 or apply a jumper on P24 by shorting the two uppermost pins as shown in the figure above.
