Affordable and flexible platform to ease prototyping using a STM32F401RET6 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.

These headers give access to all STM32 pins.
Only the labels written in blue/white or green/white (i.e. PA_4, PB_5, A0, D14, LED1...) must be used in your code. The other labels are given as information (alternate-functions, power pins, ...).
You can find more details on the available pins and labels in the following files (link to the latest mbed-dev library version):
Shields support notes
- (1) - This shield requires SPI pins remapping because it uses a non-standard 6 pin SPI connector. Please refer to the shield page on mbed for more information.
- (2) - To use this shield with ST Nucleo platforms you will need to remove SB13 and SB14 then bridge SB62 and SB63. This will enable the processor to communicate with the shield using the default serial connection, but will stop the comms going via the ST-Link and USB. Alternatively you could use other serial-enabled pins, which have to be connected to D0/D1 pins on the shield. Please refer to the the Nucleo pinout image for options.
- (3) - This shield uses I2C on A4/A5 pins and requires bridging of A4<->D14 and A5<->D15.
- (4) - To boot on external power, the PWR jumper (near the reset button) has to be switched to E5V position.
