What voltage is supplied?

[NY]

Hello.

I am measuring the current of nRF52832 using Power Profiler Kit(PPK).

I used the following case with PPK setting.

At this time, how much voltage is supplied to nRF52?

And, how do I change the voltage supplied to nRF52?

Hi,

The voltage is whatever you specify in the PPK software:

Note that Adjusting the voltage will only have an effect if the power is supplied by the on-board regulator (the Power select (SW4) switch is in the "Reg" position).

EDIT 08.01.2018:

It seems like I have to make a slight correction.

As long as you have the PPK mounted on top of the DK you are measuring on, the Voltage regulator setting in the PPK software needs to match the voltage on the DK underneath. Otherwise you will get current leakages and inaccurate measurements.

If you want to measure currents while adjusting the voltage you will have to measure on an external device as is shown here.

In my use case the SW4 switch is in the "DK" position.

I used the following use case.

Can I change the supply voltage in this use case?

Thank you for your reply.
