NRF54L15DK sleep mode Current measurement

I got setup and measurement values with plugged and unplugged USB-C Cable mixed up. If the cable has to be plugged in, my problem is solved and the values i am measuring are correct. Thanks

It should be plugged in for this. While the rest of the DK is powered, you will only measure nRF54L15 current consumption with your setup still.

[quote user="JonasZ"]No, im measuring 0.8mA.[/quote]

But you first said "I´m measuring around 0,45mA when in system off mode. " and then "Disabling the VCOMs decreased my current consumption to 0.8 mA.".

How can it decrease from 0.45mA to 0.8mA?

No, im measuring 0.8mA. Is there any other way to decrease the current? The USB-C Cable has to be unplugged for this measurement right?

Disabling the VCOMs decreased my current consumption to 0.8 mA. Thanks for the help

Hi,

Try to use the Board Configurator to disable VCOMs on the DK. Does that decrease the consumption some?

Also, which version is the DK?
