The whole series of NUCLEO development boards is equipped with a STM32 microcontroller based on ARM Cortex-M family, adopting a 32-bit RISC architecture. This means extremely high performance microcontroller for serious applications (image processing, real time control, high speed procesing applications).

The NUCLEO development boards, produced by STMicroelectronics, keeps compatibility with Arduino expansion connectors so that we can use its commonly available shields. Provided with the STM32 Nucleo boards, the STM32Cube software packages come with several examples. All STM32 Nucleo users have free access to the mbed online resources (compiler, C/C++ SDK, and developer community)
