15 / 43 page SARA-R4 series - Data sheet UBX-16024152 - R18 Interfaces Page 15 of 43 2.6 Audio ☞ Audio is not supported by the “00”, “01”, “02”, “52”, “63” and “73” product versions. SARA-R4 series modules support VoLTE (Voice over LTE Cat M1 radio bearer) for providing audio services. SARA-R4 series modules include an I2S digital audio interface to transfer digital audio data to/from an external compatible audio device. The digital audio interface can be made available as an alternative function, in a mutually exclusive way, over the SPI interface pins (I2S_WA / SPI_MOSI, I2S_RXD / SPI_MISO, I2S_CLK / SPI_CLK, I2S_TXD / SPI_CS). 2.7 GPIO SARA-R4 series modules include pins that can be configured as general purpose input/output or to provide custom functions as summarized in Table 4 (for further details, see the SARA-R4 series system integration manual [2] and the SARA-R4 series AT commands manual [1]). Function Description Default GPIO Configurable GPIOs Network status indication Network status: registered / data transmission, no service -- GPIO1 GNSS supply enable 19 Enable/disable the supply of a u-blox GNSS receiver connected to the cellular module by the DDC (I2C) interface -- GPIO2 GNSS data ready 19 Sense when a u-blox GNSS receiver connected to the module is ready for sending data by the DDC (I2C) interface -- GPIO3 SIM card detection SIM card physical presence detection -- GPIO5 Ring Indicator 20 Events indicator -- RI Module status indication Module switched off or in PSM low power deep sleep mode, versus active or connected mode -- GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6 Last gasp 20 Input to trigger last gasp notification -- GPIO3, GPIO4, GPIO6 LwM2M pulse 21 Output to notify a settable LwM2M event with a configurable pulse -- GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6 General purpose input Input to sense high or low digital level -- GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6 General purpose output Output to set the high or the low digital level -- GPIO1, GPIO2, GPIO3, GPIO4, GPIO6 Pin disabled Tri-state with an internal active pull-down enabled GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, RI GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, RI Table 4: GPIO custom functions configuration 19 Not supported by “00” and “01” product versions 20 Not supported by “00”, “01” and SARA-R410M-02B-00 product versions 21 Not supported by “00”, “01” and “x2” product versions |
