[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?

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,
