STMicroelectronics' highly affordable STM32 Nucleo development 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 includes Arduino Uno Rev3 and ST Morpho connectors while the Nucleo-32 includes 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's MDK-ARM™, mbed™, and GCC/LLVM-based IDEs. All STM32 Nucleo users have free access to the mbed online resources (compiler, C and C++ SDK, and developer community) at www.mbed.org, allowing the user to build a complete application in only a few minutes.

STM32 Nucleo boards are available with 32 (Nucleo-32), 64 (Nucleo-64), and 144 (Nucleo-144) pin microcontrollers. All of the Nucleo-64 development boards are also compatible with the STM32 Open Development Environment.
