STM32H7 Nucleo-144 boards (MB1364)
Introduction
The STM32H7 Nucleo-144 boards based on the MB1364 reference board (NUCLEO-
H723ZG, NUCLEO-H743ZI (Order code NUCLEO-H743ZI2), and NUCLEO-H753ZI)
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 Series 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-V3 debugger/programmer. The
STM32H7 Nucleo-144 boards come with the comprehensive free software libraries and
examples available with the STM32Cube MCU Package.
