PCA10040 - any pins to measure current consumption of the SOC?

[Alex Co]

Hi

I am using PCA10040 in order to develop nrf52 firmware. For now I would like to try to measure current consumption.

Is there any couple of pins on the board I can use to connect a multimeter or related device to briefly measure current consumption?

Thanks

Alex

This is described in the User Guide!

Note that a multimeter is not a very effective tool for this - because of the very "peaky" nature of the current.

Take a look at the Power Profiler Kit:

Other tools are available; eg,

The image above was acquired using a current-sense amplifier and an oscilloscope.
