Smart Machine Smart Decision
Note
：
SDA and SCL do not have pull-up resistors in module. So, 2 external pull up resistors are
needed in application circuit.
“AT+CRIIC and AT+CWIIC” AT commands could be used to read/write register values of the
I2C peripheral devices. For more details about AT commands please refer to document [1].
3.9 SDIO Interface
SIM7600SA-H provides a 4 bit 1.8V SDIO interface for WLAN solution.
The default WLAN IC is QCA9377, and the application need software support.
This part do not support now, need for future develop.
3.10 SPI Interface
SIM7600SA-H provides a SPI interface as a master only. Its operation voltage is 1.8V, and its
clock rate is up to 26 MHz.
Note
：
For more details of the AT commands about the SPI, please refer to document [1].
3.11 Network status
The NETLIGHT pin is used to control Network Status LED, its reference circuit is shown in the
following figure.
