* In above table the current consumption value is the typical one of the module tested in laboratory. In the mass production stage,
there may be differences among each individual.
6.9 Electro-Static Discharge
SIM808 is an ESD sensitive component, so more attention should be paid to the procedure of handling and
packaging. The ESD test results are shown in the following table.
