The highly affordable STM32 Nucleo boards allow anyone to try out new ideas and to quickly create prototypes with any STM32 MCU.

Sharing the same connectors, STM32 Nucleo boards can easily be extended with a large number of specialized application hardware add-ons (Nucleo-64 include Arduino Uno rev3 & ST morpho connectors, Nucleo-32 include Arduino Nano connectors).

The STM32 Nucleo boards integrate an ST-Link debugger/programmer, so there is no need for a separate probe.

A comprehensive STM32 software HAL library together with various software examples are provided with the STM32 Nucleo boards, and seamlessly work with a wide range of development environments including IAR EWARM, Keil MDK-ARM, mbed and GCC/LLVM-based IDEs.

All STM32 Nucleo users have free access to the mbed online resources (compiler, C/C++ SDK, and developer community) at allowing to build a complete application in only a few minutes.

STM32 Nucleo ecosystem

STMicroelectronics is extending its range of STM32 Nucleo development boards with scalable, small-form-factor variants to support the tiny 32-pin members of its STM32 microcontroller family. The new STM32 Nucleo-32 boards (NUCLEO-L011K4NUCLEO-F031K6NUCLEO-F042K6NUCLEO-L031K6,NUCLEO-F303K8NUCLEO-L432KC) come with direct support from a wide choice of IDEs and direct access to mbed online resources. Thanks to their reduced footprint, the STM32 Nucleo-32 boards provide additional flexibility for prototyping, and may be expanded with specialized add-on boards using Arduino nano connectivity.

Developers will appreciate the new slim-form-factor NUCLEO-L432KC board – the first Nucleo-32 board integrating the new QFN32 package - and get direct access to ARM® mbed™ online tools.
