GSM/GPRS Module Series
M66 Hardware Design
M66_Hardware_Design Confidential / Released 65 / 80
GPRS Class 12 is the default setting. The module can be configured from GPRS Class 1 to Class 12.
Setting to lower GPRS class would make it easier to design the power supply for the module.
5.5. Electro-static Discharge
Although the GSM engine is generally protected against Electro-static Discharge (ESD), ESD protection
precautions should still be emphasized. Proper ESD handling and packaging procedures must be applied
throughout the processing, handling and operation of any applications using the module.
The measured ESD values of module are shown as the following table:
