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.
Provided with the STM32 Nucleo boards, the STM32Cube software packages come with several examples 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).
