Check serial interfaces requirements: SARA-G3 modules provide UART interface for AT command,
data communication, multiplexer functionality, FW upgrade over AT and provide auxiliary UART
interface for FW upgrade using the u-blox EasyFlash tool and for Trace log capture (debug
purpose).
Check analog audio requirements: SARA-G350 modules do not provide DC blocking capacitors at
the MIC_P / MIC_N input pins and provide supply output and local ground for an external
microphone at the MIC_BIAS / MIC_GND pins.
Check digital audio requirements: SARA-G350 modules provide a 4-wire 1.8 V interface supporting
PCM and Normal I2S modes, master role and fixed sample rate.
Check internal active pull-up / down values at digital interface input pins and the current
capability of digital interface output pins, since they are slightly different between SARA-G3 and
LISA modules.
Check SARA-G3 series modules software requirements
Not all of the functionalities available with LISA modules are supported by all the SARA-G3
modules versions. SARA-G300 and SARA-G310 modules do not support:
o Audio interfaces, DDC (I
2
C) interface, Antenna detection interface, GPIOs
o Low power idle-mode, if a 32 kHz signal at EXT32K input pin is not provided
o TCP/IP, UDP/IP, FTP, HTTP
o GNSS via Modem, AssistNow clients, Hybrid positioning and CellLocate
TM
functionalities
o Jamming detection
