Current Measurement verification using Power Profiler Kit 2

[Ridhi]

Case 1: Using nrf52832, solder bridge cut: what current values do the PPK gives : is it of the entire dev kit with all peripherals, programmer and BLE Soc or does it measure current of BLE SoC alone.

Case 2: while using external supply and ameter in series does the current accounts for entire dev kit or only the SoC

Case 3: how to measure current of SoC and sensors interfaced alone

power the dev kit with coin cell

PPK kit powered by usb and 

cut SB9 on nrf52832 measuring from P22 

So, in this case how will i get total current measurement for sensors, and nrf52

[Stian Røed Hafskjold]

Yes, you can measure the current through P22. But to add the current for the sensors, they will have to be powered from VDD_nRF (on P20), so connect all VDD pins on the sensors to the VDD_nRF on P20, and the PPK will measure the current for both the nRF52 and the sensors on P22.
