STM32H7 Nucleo-144 boards (MB1363)
Introduction
The STM32H7 Nucleo-144 boards based on the MB1363 reference board (NUCLEO-
H745ZI-Q, NUCLEO-H755ZI-Q, NUCLEO-H7A3ZI-Q) provide 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 STM32H7
®
microcontroller. The ST Zio connector, which extends the ARDUINO
Uno V3 connectivity,
and the ST morpho headers provide an easy means of expanding the functionality of the
Nucleo open development platform with a wide choice of specialized shields. The STM32H7
Nucleo-144 boards do not require any separate probe as they integrate the STLINK-V3E
debugger/programmer. The STM32H7 Nucleo-144 boards come with the comprehensive
free software libraries and examples available with the STM32Cube MCU Package.
