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?

Thanks. I have already checked BOM, many components supports wide temp range but few like crystals does not support.

Looking at the BOM I haven't found any components that doesn't support the temperature range you require.
Could you please specify which components you found that doesn't support the temperature range?

Best regards,

Hi Joakim,

The Crystal part 7M-12.000MAAJ-T supports only -20 to +70, the last 'A' in the part number specifies -20 to +70ºC.

Thanks.
