NOTE:
If not used, almost all pins must be left disconnected. The
only exceptions are the following pins:
(1) Available only on GE864-GPS (in case of GE864-QUAD V2 it has to
be considered RESERVED)
NOTE:
Only for GE864-GPS, do not leave the GPS_ON_OFF (ball J4)
input pin floating. It’s suggested to connect a pull-down
(e.g.: 100k).
NOTE:
RTS must be connected to the GND (on the module side) if flow
control is not used.
