How to measure the low power consumption of nRF54L15 on the nRF54L15-DK 0_9_3 board?

[Colin]

Hello! I purchased some nRF54L15-DK 0_9_3 boards. Recently, I have been conducting relevant tests on the nRF54L15-DK 0_9_3. I want to test the low power consumption performance of nRF54L15, but I don't know how to operate it. I'm also unsure about how to connect it. Can I test it by connecting the VBUS wire of the nRF54L15-DK 0_9_3? If not, please provide me with detailed instructions on testing the low power consumption performance of nRF54L15. Looking forward to your reply. 你好!我购买了一些nRF54L15-DK 0_9_3板。最近，我一直在对nRF54L15-DK 0_9_3进行相关测试。我想测试nRF54L15的低功耗性能，但是我不知道如何操作。我也不确定如何连接它。我可以通过连接nRF54L15-DK 0_9_3的VBUS线进行测试吗？如果没有，请提供给我关于测试nRF54L15低功耗性能的详细说明。期待您的回复。

Best wishes. 最好的祝福。

Hi Colin,

I want to test the low power consumption performance of nRF54L15, but I don't know how to operate it.

For general knowledge on how to work with the 54L15 as well as other nRFs, you can have a look at our DevAcademy here. For low power consumption, have a look at the LP uart sample. Though there are a few things to keep in mind to get low power consumption, like for instance disabling unused peripherals etc. 

I'm also unsure about how to connect it.

I am not sure if I understand. Connecting the DK? For how to connect it for current measurements see here, for how to connect it to use it in general, connect a USB C to J3

Hi Elfving，

Thank you for your explanation. It has been very helpful to me. I think I have a general idea of how to proceed. I'll verify it.
