STM32 Nucleo boards
Introduction
The STM32 Nucleo board (NUCLEO-F030R8, NUCLEO-F072RB, NUCLEO-F103RB,
NUCLEO-F302R8, NUCLEO-F334R8, NUCLEO-F401RE, NUCLEO-F411RE, NUCLEO-
L053R8, NUCLEO-L152RE) provides an affordable and flexible way for users to try out new
ideas and build prototypes with any STM32 microcontroller lines, 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
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. The STM32 Nucleo board comes with the STM32 comprehensive
software HAL library together with various packaged software examples, as well as direct
access to mbed online resources at mbed.org.

1 Ordering information
Table 1 lists the order codes and the respective targeted MCU.
The meaning of NUCLEO-TXXXRY codification is as follows:
•TXXX describes the STM32 MCU product line
•R describes the pin count (R for 64 pins)
•Y describes the code size (8 for 64K, B for 128K, E for 512K)
The order code is printed on a sticker placed at the top or bottom side of the board.

3 Quick start
The STM32 Nucleo board is a low-cost and easy-to-use development platform used to
quickly evaluate and start a development with an STM32 microcontroller in LQFP64
package.
Before installing and using the product, please accept the Evaluation Product License
Agreement from www.st.com/stm32nucleo.
For more information on the STM32 Nucleo boards and to access the demonstration
software, visit www.st.com/stm32nucleo.
3.1 Getting started
Follow the sequence below to configure the STM32 Nucleo board and launch the demo
software:
1. Check the jumper position on the board, JP1 off, JP5 (PWR) on U5V, JP6 on (IDD),
CN2 on (NUCLEO) selected.
2. For correct identification of all device interfaces from the host PC, install the Nucleo
USB driver available on www.st.com/stm32nucleo, prior to connecting the board
3. Connect the STM32 Nucleo board to a PC with a USB cable ‘type A to mini-B’ through
USB connector CN1 to power the board. The red LED LD3 (PWR) and LD1 (COM)
should light up. LD1 (COM) and green LED LD2 should blink.
4. Press button B1 (left button).
5. Observe how the blinking of the green LED LD2 changes according to clicks on button
B1.
6. The demo software and several software examples on how use the STM32 Nucleo
board features are available on www.st.com/stm32nucleo.
7. Develop your own application using the available examples.
3.2 System requirements
•Windows PC (XP, Vista, 7, 8)
