Product overview
Description
X-CUBE-CELLULAR consists of a cellular middleware, a set of projects (for various hardware setups), and an application example for STM32 microcontrollers acting as hosts for cellular connectivity applications. The STM32 microcontrollers supported are chosen for their low-power capabilities.
The LTE Cat M or NB-IoT modems with possible 2G fallback connect to the STM32 boards directly through an STMod+ adapter or by means of an ARDUINO® / STMod+ adapter.
Some hardware solutions such as the B-L462E-CELL1 embed a dedicated circuit like the ST4SIM-200M to enforce security.
The X-CUBE-CELLULAR Expansion Package enables users to connect to the Internet through the cellular network by using the provided baseline, and to accelerate their end-product design cycle.
The cellular connectivity is achieved out-of-the shelf by means of a preprovisioned eSIM (Truphone®) embedded on some hardware version, or using a plastic SIM card that can be ordered from Sierra Wireless, an authorized partner member of the STMicroelectronics partner program.
Additional and regularly updated information, including supported hardware, is available from STMicroelectronics MCU wiki at wiki.st.com/stm32mcu. The release note available in the X-CUBE-CELLULAR Expansion Package provides an up-to-date list of supported hardware.

Follow issues and share solutions on Github for STM32Cube MCU packages. Integrate your own software components in a STM32Cube Expansion for STM32CubeMX and STM32CubeIDE tools, thanks to the new STM32PackCreator utility
STM32CubeMX is part of the STM32Cube initiative designed to simplify and accelerate the development of applications for STM32 microcontrollers. STM32CubeMX offers the possibility to generate C projects using embedded software offers packages like CMSIS-Pack compliant software packs. Starting with the 6.0.0 revision, STM32CubeMX is delivered with STM32PackCreator, an STM32 pack creation graphical companion tool, whose main purpose is the creation of software packs.
The STM32Cube.AI is an extension pack of the widely used STM32CubeMX configuration and code generation tool enabling AI on STM32 Arm® Cortex®-M-based microcontrollers.
