Hello, STM32WB55 Power Consumption measurement with STM32 Nucleo Expansion Board which has Microcontroller STM32L496.

[chinmaydixit]

I am Attaching Observed Current Consumptions.

I am observing Huge Difference between claimed current value versus observed current value at various low power modes. I am having right Connections as mentioned in Power Consumption measurement board Datasheet just to measure only current consumptions at Microcontroller and not at other devices such as Regulator, STLink, SMPS and so on which are present on STM32WB55.

Please Correct me if am wrong or Suggest me the exact connections to measure exact current at Microcontroller.

Thanks in Advance.

Hi,

do you measure the current on JP2 and supply power to the board via USB or you supply the power on JP2?

I think all the jumpers on JP5 need to be removed too.

Regards.
