Affordable and flexible platform to ease prototyping using a STM32L432KCU6 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)
By default the PA_5 (A4) and PA_6 (A5) pins can only be used as Input floating (ADC function). Remove SB16 and SB18 solder bridges in order to use these pins as Digital output and have access to other functions (DigitalOut, SPI, PWM, etc...). Refer to the user manual for more details.
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.
- Starting from MBED-OS version 5.6.2 (= mbed2 rev 153), you need to update the ST-Link FW to version V2J29M18 (or above) in order to boot (see HERE for more details)
