Power profiler voltage

[mich_x]

I am using power profiler with nRF52840 SDK. And I have measured the current of the board. But I want to calculate the energy consumption of my program. How can I get the voltage reading from power profiler? Is it 5V or somewhere I can read about in the specs

Hello mich_x

The power profile kit delivers power to the nRF DUT via the VDD_nRF pin on header P20, and it will nominally be approximately 3V. You can measure the voltage between ground and the pin of P22 which is located closest to P23.

You can find the nRF52840 specification here, the PPK user guide here, the nRF52840 preview kit hardware files here and the power profiling kit hardware files here.

Best regards
