Hi Lorenzo,

Thank you for your patience.

Yes, you can use PPK2 to do the power measurements, and it would be current measurement.
If you are using debug board (PCA64131) with the nrf-desktop-keyboard-reference-design (PCA20037), then after connecting/inserting the debug board into the keyboard designated port, you probe between the two pins on the pin-header labelled P2.

Regarding the voltage range, it should be respecting the voltage limits of the SoC, that is NRF52832 used on the Keyboard.

/BR, Naeem

Thanks. Can you please address also the two other questions above, about Source Meter vs Ampere meter in PPK2 and about the voltage range?

thanks

Hello,

The documentation shows which boards could be connected to this debug port.

Also, it mentions that the debug board can be used for programming and powering the device.
