PERFORMANCE PARAMETER

Absolute Maximum Ratings
Parameter	Symbol	Min.	Max.	Unit
Power supply voltage	VCC	-0.5	+3.6	V
Storage temperature	TC	-40	+85	℃
Relative humidity	RH	0	85	%
These values represent the damage threshold of the module.Stress in excess of any of the individual absolute maximum ratingscan cause immediate catastrophic damage to the module even if all other parameters are within recommended operating conditions.
