Affordable and flexible platform to ease prototyping using a STM32F446RET6 microcontroller.
Table of Contents
The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features.
The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.
The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer.

You can find more details on the available pins and labels in the PeripheralPins.c and PinNames.h files.
These files can be found in:
- ARMmbed/mbed-os repository on GitHub (up-to-date version, used with mbed CLI commands)
- mbed-dev library in developer.mbed.org (source files of the mbed library used on mbed compiler IDE)
These headers give access to all STM32 pins.
ST X-NUCLEO boards¶
Other Non-ST boards¶
This video shows how to get started with ARM mbed Integrated Development Environment using STM32 Nucleo platform:
Nucleo ST-LINK/V2 driver installation and firmware upgrade
For more information, please refer to:
The following section describes known limitations of the platform. Note that general issues are tracked into the mbed repository available on GitHub.
- On Nucleo 64-pins boards, the D0 and D1 pins are not available per default as they are used by the STLink Virtual Comm Port. More information HERE
