Overview

The NUCLEO-H755ZI-Q is a high-performance development board featuring the dual-core STM32H755ZI microcontroller with Arm Cortex-M7 and Cortex-M4 cores. This Nucleo-144 board includes an internal SMPS for optimized power consumption and integrated cryptography hardware for secure applications. It provides a flexible prototyping platform with an on-board STLINK-V3E debugger, Ethernet support, and a USB OTG FS micro-AB connector.

Why Choose This Part

The dual-core architecture allows for a clear separation between real-time tasks on the Cortex-M4 and complex application logic on the Cortex-M7. The inclusion of an internal SMPS significantly improves power efficiency during high-performance operation compared to traditional LDO-only variants. The Nucleo-144 form factor offers extensive I/O access through ST Zio and morpho connectors, ensuring compatibility with a wide range of shields and custom hardware.

Applications

Industrial Gateway
Utilizing the integrated Ethernet and dual-core architecture to manage communication protocols on one core while handling real-time control on the other.
Edge AI Inference
Leveraging the high-frequency Cortex-M7 core and FPU to run optimized machine learning models at the network edge.
Secure IoT Endpoints
Using built-in cryptography hardware to implement secure boot, encrypted communication, and data protection in connected devices.
Motor Control Prototyping
Taking advantage of the high-pin count LQFP144 package and advanced timers to develop complex multi-axis motor control algorithms.
