Introduction
The Nucleo-64 board based on the MB1841 reference board (NUCLEO-U545RE-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 series microcontroller.
®
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 STM32 Nucleo-64 board does not require any separate probe as it integrates the STLINK-V3EC debugger/programmer.
The STM32 Nucleo-64 board comes with the STM32 comprehensive free software libraries and examples available with the
STM32CubeU5
MCU Package.
