Measurement of current consumption in MCU

[HNdal]

I have a Nucleo 64 STM32F303RE, I would like to measure the current consumed by the MCU while running application. How do I do it ?

Check the UM1724 User manual STM32 Nucleo-64 boards. There are schematics at the end. Measure the current at JP6.

Yes thank you,one more thing,

I supposed this can be done with the board supplied by USB?,

In this case , the voltage supplied to MCU will be measured between VDD and ground.

Yes.

I suggest to additionally consult the schematics, to see where you measure, and what.

Thank you so much.

Hello @HNdal​ ,

You can measure the current consumption on the IDD JP6 jumper.

Thank you so much, and the voltage accross the MCU would be between VDD and VSS pins?

right.
