To measure current, you must first prepare the Development Kit (DK).
The suggested configurations split the power domains for the nRF7002 DK and the rest of the DK.
Figure 1. Preparing the DK for current measurements
- To put P23 in series with the load, remove the VBAT jumper cap.
- To restore normal DK function after measurement, apply a jumper on P23.
- To reprogram the nRF5340 SoC while the DK is prepared for current measurements, remove measurement devices from P23 and then connect the USB cable.
