Temperature range supported by nRF52840-DK and USB dongle

[Gopi]

What is the operating and storage temperature range of nRF52840-DK development kit and USB dongle? We need to use these evaluation boards at a temperature range of -20 to +80 degree, Is this ok?

Hi. 

You can find the Absolute maximum ratings here: 
Absolute maximum ratings

and the Recommended operating conditions here: 
Recommended operating conditions

As stated in the nRF52840 PS: 

Symbol	Parameter	Notes	Min.	Nom.	Max.	Units
TA	Operating temperature		-40	25	85	°C

Please confirm this is applicable for all components on the Development kits also. We will be using the nRF52840-DK or USB dongle for evaluation purpose where temperature cane extend to -20 to +80 degrees.

Thanks.

I can't confirm that the temperature range is valid for all the components on the DK / Dongle.
I've forwarded your question to our team in charge of developing the development kits. 

I'll get back to you with an answer from them. 

Best regards,

As a development kit, I would assume that it's intended for use in a normal "development" environment - so probably not at those temperature extremes.

But interested to hear Nordic's reply ...

[Joakim Jakobsen]

That is true. I don't think the development kit or the dongle was developed to match the temperature range of the SoC. 

We need to look through the BOM for the nRF52840 DK and Dongle in order to determine if there are any components that doesn't match the temperature range. 
We don't have the resources available to do this until next week. 

The HW files and BOM are available for download at nordicsemi.com
