☞ SARA-R404M-00B and SARA-R410M-01B modules, i.e. the “00” and “01” product versions of the
SARA-R4/N4 series modules, do not support the following interfaces, which should be left
unconnected and should not be driven by external devices:
o DDC (I
2
C) interface
o SDIO interface
o SPI interface
o Digital audio interface
☞ SARA-R410M-02B, SARA-R410M-52B, SARA-R412M-02B, SARA-N410-02B modules, i.e. the “02”,
and “52” product versions of the SARA-R4/N4 series modules, do not support the following
interfaces, which should be left unconnected and should not be driven by external devices:
o SDIO interface
o SPI interface
o Digital audio interface
