    4 INTERFACES 4.1 Interface Voltage Selection The LTE910CF is equipped with a variable voltage interface solution. This allows the user to match the device to the system’s level without extra hardware. Once a voltage has been injected, the unit will swap to the chosen voltage immediately for the affected I/O.

    • Parity: None • Hardware Handshaking: Yes The LTE910CF does not support autobaud, and must be changed via the AT+IPR command. It is defaulted to 115200 bps Note: If you are not using Hardware Handshaking, please note that RTS must be connected to GROUND for proper communications where flow control is unused.

    4.7.4 I2C The I2C interface is an alternate function of the modem’s GPIO, for the LTE910CF, those two signals are designated for GPIO 9 (SDA) and GPIO 10 (SCL) and are 1.8V logic level to match the DVI interface for easy usage with a codec. The signals are not pulled up on the Plug-In module and must be pulled up externally as they may also be used as spare GPIO.
