Everything you wanted to know about ST on Mbed, but were afraid to ask


By choosing one of ST's STM32 microcontrollers for your embedded application, you gain from our leading expertise in MCU architecture, technology, multi-source manufacturing and support.

ST's product portfolio contains a comprehensive range of microcontrollers, from robust, low-cost 8-bit MCUs up to 32-bit ARM-based Cortex™-M0, Cortex™-M3, Cortex™-M4 and Cortex™-M7 Flash microcontrollers with a great choice of peripherals. ST has also extended this range to include an ultra-low-power MCU platform.

Extensive support through a combination of flexible and powerful development tools, training courses, consultancy and web support gives you a plus for a faster time to market.

The STM32 family of 32‑bit Flash microcontrollers based on the ARM Cortex™‑M processor is designed to offer new degrees of freedom to MCU users. It offers a 32‑bit product range that combines high performance, real-time capabilities, digital signal processing, and low‑power, low‑voltage operation, while maintaining full integration and ease of development.

The unparalleled and large range of STM32 devices, based on an industry-standard core and accompanied by a vast choice of tools and software, makes this family of products the ideal choice, both for small projects and for entire platform decisions.


STM32 Nucleo expansion boards provide additional functionality to add sensing, control, connectivity, power, audio or other functions as needed.
They carry all the required components to

  • Evaluate ST devices to be used together with an STM32 microcontroller
  • Build STM32-based applications leveraging functionality and performance of ST’s device portfolio.

The expansion boards are equipped with standardized interconnections, such as Arduino Uno R3 connector, or a Morpho connector for a higher level of connectivity.
The combination of STM32 Nucleo boards and expansion boards is a unified scalable approach with unlimited possibilities for application development, prototyping or product evaluation.
