ARM mbed + Arduino + STM32 MCUs in extensible development platform

February 18, 2014 // By Graham Prophet
A series of low-cost STM32 Nucleo prototyping/development boards deliver a combination of ARM Cortex-M-based microcontroller development boards, on an mbed platform, that add extensibility by providing headers for Arduino shields and direct connectivity to microcontroller peripherals. ST will introduce the boards at Embedded World and from Q2 2014 there will be an STM32 Nucleo board for every STM32 line.

The STM32 Nucleo boards are mbed-enabled, and support Arduino connectivity while also providing ST Morpho extension headers that allow access to all of the microcontroller’s on-chip peripherals. As an mbed-enabled board, developers can make use of the mbed open source software platform, online tools and collaboration infrastructure at The board’s Arduino headers accept shields from the extensive Arduino ecosystem, allowing developers to add specialised functionality quickly and easily. ST will also offer its own dedicated shields supporting functions such as Bluetooth LE or Wi-Fi connectivity, GPS, audio recording, exploiting the company’s MEMS microphone expertise, proximity sensing, and wireless control.

Full STM32 Nucleo support for the STM32 family allows agile development with fine-tuning of both hardware and software on-the-fly at each prototyping stage. Your investment in application shields is also protected, as any shield can be re-used with any STM32 Nucleo board and across various projects.

The first four STM32 Nucleo boards, supporting the STM32 F1, L1, F4, and F0 Value lines, will appear at Embedded Word 2014 in Nuremberg, February 25-27, where 2,200 STM32 Nucleo boards will be given away to visitors that have registered at ST’s website. Further introductions will add support for the STM32 F3, L0, and F0 lines in Q2 2014.

The STM32 Nucleo-F030R8, STM32 Nucleo-F103RB, STM32 Nucleo-F401RE and STM32 Nucleo-L152RE are available immediately, priced from $10.32 per unit. The STM32 Nucleo-F072RB, STM32 Nucleo-F302R8, STM32 Nucleo-F334R8, and STM32 Nucleo-L053R8 boards will be introduced during Q2 2014.
