nRF52840 Current Consumption

Hello Team,

We have used the 451-00001 Laird module in our design. We are currently working on optimizing the sleep mode current. As of now, we are getting for device <100uA where nrf52840 only taking 1uA. We are able to test a few samples on that board and found the same results. Now, for a few boards, we are seeing sleep mode current consumption of ~400uA for the device where nRF52840 current is 300uA. 

We checked all the interfaces which we have turned off as a part of sleep mode and it's working fine on all the boards.

Also, we checked the assembly issue but still we are unable to find anything.

Kindly guide us to narrow down to identify the root cause.

Regards,

Pratik Panchal
