14.3. Debug of the GE/GC864-QUAD V2 AND GE864-
GPS in Production
To test and debug the mounting of GC/GE864-QUAD V2 and GE864-
GPS , we strongly recommend to foreseen test pads on the
host PCB, in order to check the connection between the
GE/GC864-QUAD V2 and GE864-GPS itself and the application and
to test the performance of the module connecting it with an
external computer. Depending by the customer application,
these pads include, but are not limited to the following
signals:
