6 Quick start
The STM32 Nucleo-64 boards are low-cost and easy-to-use development kits, to quickly evaluate and start
development with an STM32U3 series or STM32U5 series microcontroller in an LQFP 64‑pin package. Before
installing and using the product, accept the evaluation product license agreement from the
webpage. For more information on the STM32 Nucleo-64 board and the software example, visit the
stm32nucleo webpage.
6.1 Getting started
Follow the sequence below to configure the Nucleo-64 board and launch the demonstration application (refer to
Figure 5 and Figure 6
1. Check the jumper position on the board (refer to Default board configuration).
2. Connect the Nucleo-64 board to a PC with a USB cable (USB Type-A or USB Type-C
through the USB connector (CN1) to power the board.
3. The 5V_PWR green (LD3), COM (LD1), and PWR (LD4) LEDs light up, and the green LED (LD2) blinks.
4. Press the blue user button (B1).
5. Observe how the blinking of the LED (LD2) changes, according to the clicks on the button (B1).
6. Download the demonstration software and several software examples that help to use the STM32 Nucleo-64
features. These are available on the
7. Develop your application using the available examples.
6.2 Default board configuration
By default, the Nucleo-64 board is configured with VDD_MCU at 3.3 V. It is possible to configure the board with
VDD_MCU at 1.8 V. Before switching to 1.8 V, ensure that the extension module and external shield connected to
the Nucleo-64 board are 1.8 V compatible.
