STM32 MCU Eval Tools  

ST's tools for evaluation of the STM32, range from highly affordable community enabled tools up to fully equipped boards, ready for evaluation of every single feature of the selected MCU. All ST evaluation boards include an ST-LINK/V2 in-circuit debugger/programmer.
STM32 Nucleo boards follow a lean approach and are ideal for prototyping and community usage. An Arduino™connector and the ST Morpho connector make an extension with application related add-on hardware easy. All I/Os of the MCU are easily accessible, the boards come with a HAL library and work with IAR, Keil, CCC based IDEs as well as the mbed™ online IDE.
STM32 Discovery kits are a cheap and complete approach for evaluation of the outstanding capabilities of STM32 MCUs. They carry the necessary components, like MEMS microphones, sensors, LCD displays) for demonstration of specific device features. Evaluation and prototyping are facilitated by a HAL library and software examples, IAR, Keil and CCC based IDEs are supported.
STM32 Eval boards, the high end evaluation platform, carry all the required external hardware necessary for using the complete features set of an STM32 Microcontroller. STM32 Eval boards give access to all the pins of the contained microcontroller, even for bigger packages. The HAL library and ready-to-use software examples make application design very easy.
This comprehensive portfolio of evaluation boards is complemented by a wide choice of STM32 evaluation boards developed by ST’s partners.

STM32 MCU Nucleo  

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 www.mbed.org allowing to build a complete application in only a few minutes.
