Minimum ESD Protection Levels ESD/Input Voltage
Charge Device Model
EIA/JEDEC22-C101-A
500 V
RF Antenna IEC 61000-4-2 8000 V
As the integrator, it is your responsibility to protect the Enabler IIIG module from
electrical disturbances and excursions that exceed the specified operating
parameters.
Antenna
The GSM0308/GSM0306 module has one RF antenna connection on the module. The
connection is for the GSM section of the module.
Control Connector Signal Functions
Please note that we included the following descriptions to provide hardware-
level definitions. In some cases, specific lines will have no firmware functionality
implemented. We included information for each hardware-specific feature in the
appropriate section.
Module Power (Pins 85, 87, 89, 91, 93, 95, 97, 99)
The Novatel Wireless M2M Enabler IIIG module uses a single voltage source of VCC=+3.3V to
4.5V. (The exact values of the uplink currents are shown in the tables in section 5.3.1.)
