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

1). if i have sensors connected to VDD on P13 will it be ok or is it mandatory to connect them on P20

2). how will i connect 2 sensors i nrf52832 board P20 as in that only one vdd is there

VDD on P13 is not part of the current that goes to VDD_nRF, so it will not be measured when measuring the current through P22.

If you want to connect two wires to the the VDD_nRF pin on P20, you will have to be creative. Split the wire, use a breadboard, solder the wires on the header, use crocodile clips, etc. There are many possibilities.
