6.4. Circuit Protection

Other than very low level ESD protection within the module's integrated circuits, the module does
not have any protection against ESD events or other excursions that exceed the specified
operating parameters.
Generally, ESD protection (typically TVS/Transzorb devices) should be added to all signals that
leave the host board. This includes V
Series resistors (typically 47 Ω) can also be added in series with data lines to limit the peak
current during a voltage excursion.

Caution – It is the Integrator's responsibility to protect
the Enabler III-G module from electrical disturbances
and excursions, which exceed the specified operating
parameters.

6.5. Antenna

The GSM0308-xx module has one RF antenna connection on the module. The connection is
for the GSM section of the module.
