Reserved pins (RSVD)
SARA-G3 series modules have pins reserved for future use. All the
RSVD
pins, except pin number 33,
can be left unconnected on the application board.
illustrates the application circuit.
Pin 33 (
RSVD
) must be connected to GND.

Module placement
Optimize placement for minimum length of RF line and closer path from DC source for
VCC
.
Make sure that RF and analog circuits are clearly separated from any other digital circuits on the system
board.
Provide enough clearance between the module and any external part.
The heat dissipation during continuous transmission at maximum power can significantly raise the
temperature of the application base-board below the SARA-G3 modules: avoid placing temperature
sensitive devices close to the module.
