Overview
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.

Nucleo pinout
Arduino-compatible headers
Shared UART on pins D0 and D1
These pins are shared with the PC Serial connection via STLink. If you need to use these pins independently, see this page: https://developer.mbed.org/teams/ST/wiki/Use-of-D0D1-Arduino-pins
Morpho headers
These headers give access to all STM32 pins.
Information
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 also use these additional labels:
SERIAL_TX=PA_2 I2C_SCL=PB_8 SPI_MOSI=PA_7 PWM_OUT=PB_3
SERIAL_RX=PA_3 I2C_SDA=PB_9 SPI_MISO=PA_6
SPI_SCK =PA_5
SPI_CS =PB_6
