A.4.7
GPIO pins
The same compatible external circuit can be implemented for SARA-G340 / SARA-G350 and LISA series: four
1.8 V GPIOs are provided by SARA-G340 / SARA-G350 modules, providing the same functionalities as LISA series
modules except Module Status and Operating Mode Indications. The
SIM_DET
pin provides the SIM detection
function on SARA modules rather than the
GPIO5
pin as on LISA-U2 series modules.
SARA-G300 and SARA-G310 modules do not provide GPIOs.
A.4.8
Reserved pins
SARA modules
RSVD
pin 33 must be connected to ground, as does the
RSVD
pin 5 on LISA modules.
A.4.9
Pin-out comparison between LISA and SARA-G3
Table 68 summarizes the pin electrical differences between LISA and SARA-G3 cellular modules.
