The highly affordable STM32 Nucleo boards allow to try out new ideas and to quickly create prototypes with any STM32 MCU.
Sharing Arduino connectors and ST Morpho headers, STM32 Nucleo boards can easily be extended with a large number of application related hardware add-ons. The STM32 Nucleo boards come with an integrated ST-Link debugger/programmer; no need for an external probe. The boards work with a wide range of development environments including IAR EWARM, Keil MDK, mbed, GCC-based IDEs (Atollic TrueStudio).
STM32 Nucleo users have free access to the mbed online compiler, the mbed online C/C++ SDK and the developer community at mbed.org, allowing to build a complete application in only a few minutes.
