Board only (without a case): -20°C. to 70°C.
[b]
This temperature is when power consumption is limited, such as by stopping communication of the 3G module at high temperature.
Absolute maximum ratings are values that should not be exceeded under any use
or test conditions, even just momentarily. Please factor in a margin against these
