To measure current, you must first prepare the Development Kit (DK).
The suggested configurations split the power domains for the nRF52840
System on Chip (SoC) and the
rest of the DK.
- To put P22 in series with the load, cut solder bridge SB40.
- To restore normal kit function after measurement, solder SB40 or apply a jumper on P22.
- To reprogram the nRF52840 SoC while the DK is prepared for current measurements, remove measurement devices from P22, and then connect the Universal Serial Bus (USB) cable.

measurements
