S32KEVB

Hi,

I'm looking to measure the MCU current under different power mode. in the S32KEVB schematic , I noticed

a resistor R117 between VDD and VDD_MCU and there is a shunt jumper J15 across.

 

Is this to help measure the current drawn by MCU from the supply?

if YES, how?

Do I need to populate it with a known resistor value? measure the voltage across and divide by its value?

what is VDD vs VDD_MCU?

Can not find any info for this?

 

Thanks,

Koorosh Hajiani
