Layout checklist
See
section 3.3
Is the GNSS module located according to the recommendation?
Has the grounding concept been followed?
Add a ground plane underneath the GNSS module to reduce interference.
For improved shielding, add as many vias as possible around the serial communication lines, underneath
the GNSS module etc.
Have appropriate EOS/ESD/EMI protection measures been included? This is especially important for
designs including cellular modules.
3.1.3
Antenna checklist
Make sure the antenna is not placed close to noisy parts of the circuitry. (E.g. micro-controller, display,
etc.)
3.2
Design considerations for minimal designs
For a minimal design with a PAM-7Q GPS module, the following functions and pins need consideration:
Connect the Power supply to
VCC
.
Assure an optimal ground connection to all ground pins of the module.
Choose the required serial communication interface (UART or DDC) and connect the appropriate pins to
your application.
If you need improved start-up or use AssistNow Autonomous in your application, connect a backup supply
voltage to
V_BCKP
.
