Introduction
The STM32U5 Nucleo-144 board based on the MB1549 reference board (order codes NUCLEO-U575ZI-Q and NUCLEO-
U5A5ZJ-Q) provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the
various combinations of performance and power‑consumption features provided by the STM32U5 microcontroller.
The ST Zio connector, which extends the ARDUINO
®
Uno V3 connectivity, and the ST morpho headers provide easy expansion
of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.
The STM32U5 Nucleo-144 board does not require any separate probe as it integrates the STLINK-V3E debugger/programmer.
The STM32U5 Nucleo-144 board comes with the STM32 comprehensive free software libraries and examples available with the
STM32CubeU5 MCU Package.
