5 Quick start
The STM32U5 Nucleo-144 board is a low-cost and easy-to-use development kit, to quickly evaluate and start
development with an STM32U5 Series microcontroller in an LQFP 144-pin package. Before installing and
using the product, accept the Evaluation Product License Agreement from the www.st.com/epla webpage. For
more information on the STM32U5 Nucleo-144 board and software example, visit the www.st.com/stm32nucleo
webpage.
5.1 Getting started
Follow the sequence below to configure the STM32U5 Nucleo-144 board and launch the software example (refer
to Figure 4 for component location):
1. Check the jumper position on the board (refer to Default board configuration).
2.
Connect the STM32U5 Nucleo-144 board to a PC with a USB cable (USB Type-A or USB Type-C
®
to
Micro-B) through the USB connector (CN1) to power the board.
3. The 5V_PWR green (LD5) and COM (LD4) LEDs light up, and the green LED (LD1) blinks.
4. Press the blue user button (B1).
5. Observe how the blinking of the LEDs (LD1, LD2, and LD3) changes, according to the clicks on the button
(B1).
6. Download the software examples that help to use the STM32 Nucleo features. These are available on the
www.st.com website.
7. Develop your application using the available examples.
5.2 Default board configuration
By default, the STM32U5 Nucleo-144 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-144 board are 1.8 V compatible.
The default jumper configuration and voltage setting are shown in Table 4.
