Introduction
The STM32L5 Nucleo-144 board based on the MB1361 reference board (NUCLEO-L552ZE-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 STM32L5 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 STM32L5 Nucleo-144 board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer.
The STM32L5 Nucleo-144 board comes with the STM32 comprehensive free software libraries and examples available with the
STM32CubeL5 MCU Package.
