Set nRF52840-DK in High voltage mode and measure current consumption of nRF52840 SoC

[bojan]

Hello, guys.

We would like to evaluate the current consumption of nRF52840 SoC set in High Voltage mode using nRF52840-DK.

In this thread, you have explained how to measure the current consumption of nRF52840 SoC using nRF52840-DK. However, in this thread, VDD input is used to give power supply to nRF52840 SoC which sets it in Normal voltage mode.

If we want to evaluate the current consumption of nRF52840 SoC in High Voltage mode, would it be enough to configure the nRF52840-DK the following way?

Thanks in advance for your efforts.

Sincerely,
Bojan.

Hi brian. I did the same with a 5340 board. I was really curious as to what measurements you came up with, if you would be so kind. Im seeing quite ab increase in power consumption when running in high voltage mode.
