I just bought the nRF52840 DK.  How do I put it in deep sleep mode?

hi ... you can use sd_app_evt_wait() ,it will be in  sleep mode  until you are waking up by using external or internal interrupt . you can see this link  https://devzone.nordicsemi.com/f/nordic-q-a/24398/sleep-wakeup-tutorial

What's the power consumption in this mode?

Thanks.

Hi

The product specification provides the below current consumption scenarios. Depending on what functionalities you want from your device while sleeping the current consumption will be between 0.4 and 1.86 uA in system OFF mode. 

NOTE: The Development kit will have some minuscule leakage, so you may experience higher current draws than what is stated in the PS. If you are new to working with Nordic products, we have a lot of useful tutorials here, and the Infocenter for general information about the SDK and products.

Best regards,

Simon
