To measure current, you must first prepare the Development Kit (DK).
The suggested configurations split the power domains for the application nRF5340 System on Chip (SoC) and the rest of the DK.
- To put P22 in series with the load, cut the PCB track shorting solder bridge SB40.
- To restore normal kit function after measurement, solder SB40 or apply a jumper on P22.
- To reprogram the nRF5340 SoC while the DK is prepared for current measurements, remove measurement devices from P22, and then connect the USB cable.
