Cellular software expansion for STM32Cube

ソフトウェア入手 データブリーフのダウンロード



X-CUBE-CELLULAR consists of a cellular middleware, a set of projects (for various hardware setups), and an application example for STM32L4 Series microcontrollers acting as hosts for cellular connectivity applications. The STM32L4 Series microcontrollers are used 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. Some hardware solutions embed a pre-provisioned eSIM (EMnify, Truphone®).

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.

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.
