Quick start

The STM32L5 Nucleo-144 board is a low-cost and easy-to-use development kit, to quickly evaluate and start
development with an STM32L5 Series microcontroller in LFQFP 144-pin package. Before installing and using the
product, accept the Evaluation Product License Agreement from the
information on the STM32L5 Nucleo-144 board and for demonstration software, visit the
stm32nucleo webpage.
5.1

Getting started

Follow the sequence below to configure the STM32L5 Nucleo-144 board and launch the demonstration
application (refer to
1. Check the jumper position on the board (refer to
2. For the correct identification of the device interfaces from the host PC and before connecting the board,
install the ST-LINK/V2-1 USB driver available on the
3. Connect the STM32L5 Nucleo-144 board to a PC with a USB cable (Type-A to Micro-B) through the USB
connector CN1 to power the board.
4. Then, the green LED LD6 (5V_PWR) lights up, LD4 (COM) and green LED LD1 blink.
5. Press USER button B1 (blue)
6. Observe how the blinking of the LEDs LD1, LD2, and LD3 changes, according to clicks on button B1.
7. Download the demonstration software and several software examples that help to use the STM32 Nucleo
features. These are available on the
8. Develop your application using the available examples.

Default board configuration

By default, the NUCLEO board is sent with VDD_MCU@3V3. It is possible to set the board for VDD_MCU@1V8.
Before switching to 1V8, check that extension module and external shield connected to the NUCLEO board are
1V8 compatible.
