How can I measure the sleep current for nRf5340

[shreya lingayat]

I have DK of nRF5340, I want to get started with it and create the development env, as well as I need to measure the sleep current for this module?

Any quick tutorial which I could follow to create development env?

Nordic has a powerprofiler kit with very precise current measurement, you can use it to power your application and measure power usage.

https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2

Make sure to isolate other components from influencing your measurement results.

```The nRF5340 DK is typically powered via USB, but can be powered by a wide range of sources, within the supply range of 1.7 to 5.0 V. In addition to USB, it can be powered with external source, but also includes a CR2032 battery holder and a Li-Po battery connector, for in-field testing. Current consumption can be measured by using the dedicated current measurement pins, for example by using Nordic's Power Profiler Kit II.```

Kind regards,

Berend

Hi Berend, 

Is it necessary to use the  Power Profiler Kit II, as on the DK of nRF5340 I can see something written as nRF current measurement above two pins, which made me think that there must be some sample example for this DK which I lcan load and use those pins to measure the current/power consumption when it is in sleep mode

If you remove the jumper on those pins and put a amp meter in between (a regular multimeter can do this), you can measure the current the device uses.

The powerprofiler kit is just a handy tool to measure and log current precisely.

I did find the doc explaining different ways to measure the current consumption,

Out of available sample for nRF5340, which could be the best sample if I want to know current consumption in sleep mode?

hello,

You can try to  run the system_off sample (\NCS\v2.6.0\zephyr\samples\boards\nrf\system_off) to measure the sleep current.

While trying to install SDK to program  DK with the sample you mentioned above, I'm always running into the same above error, 

I have also given try for v2.6.0, same behavior, any suggestion to pass this hurdle?
