nRF54L15 DK Current Measurement Voltage Buffer

Hello,

I´m trying to measure the current consumption on the nRF54L15-DK Rev. 0.9.2.

There are a few questions:

1) What is the role / purpose of the voltage buffer?

2) What is the difference / purpose of the VDDM_nRF and VDD_nRF Net? I would assume that there is only one VDD Domain needed?

3) Why am I supposed to disconnect the UART and SWD Lines from the debugger?

I´m feeling a bit confused about the setup of the DK and hope that you can help me.

Thanks!
