TRANSCRIPT
IntroductionThe STEVAL-STMODLTE expansion board adds LTE connectivity to evaluation boards hosting the STMod+ expansionconnector. It embeds an LTE cellular modem and an eSIM with a worldwide coverage.
The expansion board can be used only with the furnished antenna and is compatible with all STMicroelectronics Discovery kitsfeaturing an STMod+ connector, such as the STM32L496G-DISCO, and with any STMod+ compatible evaluation board.
The package, combined with any compatible evaluation board, represents an ideal development platform for cellular and cloudtechnology-based solutions.

3 X-CUBE-CELLULAR
The X-CUBE-CELLULAR cellular software expansion for STM32Cube consists of a set of libraries and applicationexamples for STM32L4 series MCUs acting as hosts for cellular connectivity applications, driving STMod+compatible cellular-modem add-on boards such as the STEVAL-STMODLTE.X-CUBE-CELLULAR enables connection to the Internet through the cellular network by using the providedbaseline and its main features are:• STMicroelectronics framework for devices based on LPWAN cellular networks• FreeRTOS™ for easy integration into a complete platform• Easy portability across different STM32 microcontroller series thanks to STM32Cube and STM32CubeMX• BSD-like socket APIs for data plane• TCP-UDP/IP connectivity with IP stack on host or modem• Flexible and modular software architecture for easy integration of other modems• PC terminal boot menu for device firmware customization (API key, APN, band)• Connected application examples

4 Modem power supply
The STEVAL-STMODLTE expansion board is supplied through the 5V on the STMod+ connector (pins 6 and 15).The modem is enabled by the power enable pin 9. When this pin is driven, a few seconds later, the red LEDswitches on indicating the modem is ready for operation, and the green LED starts flashing signaling the modemis scanning for cellular synchronization. AT command, then, can be sent via UART.If the power supply is not enough, in signaling mode, additional power supply can be provided through the USBconnector.

5 SIM selection
The STEVAL-STMODLTE offers the possibility of switching between the embedded SIM or a plastic external SIM.You just have to set Sim_select0 pin to:• LOW to select the plastic external SIM• HIGH to select the embedded SIM
