  • X-CUBE-SUBG2 is an expansion software package for STM32Cube. The software runs on the STM32 and includes drivers that recognize the Sub-1 GHz RF communication for S2-LP.

    The expansion is built on STM32Cube software technology to ease portability across different STM32 microcontrollers.
    The software comes with sample applications of P2P communication protocol, running on an X-NUCLEO-S2868A1, X-NUCLEO-S2868A2 or X-NUCLEO-S2915A1 expansion boards when connected to a compatible STM32 Nucleo development board.

    Key Features

    • Firmware package to start developing using S2-LP expansion boards
    • Point-to-point communication sample application for simple buffer transmission and acknowledgement implementation
    • Low-power optimizations for the STM32 MCU family
    • Easy portability across different MCU families thanks to STM32Cube
    • Package compatible with STM32CubeMX, can be downloaded from and installed directly into STM32CubeMX
    • Free user-friendly license terms
    • Sample implementation available on X-NUCLEO-S2868A1, X-NUCLEO-S2868A2 or X-NUCLEO-S2915A1 expansion boards when connected to NUCLEO-F401RE, NUCLEO-L053R8 or NUCLEO-L152RE development boards
