ST NUCLEO-H7S3L8 User Manual

Introduction
The STM32H7Rx/7Sx Nucleo-144 board based on the MB1737 reference board (order code NUCLEO-H7S3L8) 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 STM32H7S3L8H6 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 STM32H7Rx/7Sx Nucleo-144 board does not require any separate probe as it integrates the STLINK-V3EC debugger/
programmer.
The STM32H7Rx/7Sx Nucleo-144 board comes with the STM32 comprehensive free software libraries and examples available
with the STM32Cube MCU Package.
