5.6 Electro-static discharge
Although the GSM engine is generally protected against Electrostatic Discharge (ESD), ESD
protection precautions should still be emphasized. Proper ESD handing and packaging procedures
must be applied throughout the processing, handing and operation of any application using the
module.
The measured values of module are shown as the following table:
