STM32H5F5J-DK Discovery Kit

Introduction

The STMicroelectronics STM32H5F5J-DK Discovery Kit is a feature-rich development platform for evaluating and building applications with the STM32H5 series of microcontrollers. It combines processing capability, security-oriented features, display hardware, connectivity interfaces, sensors, and expansion options on a single board.

Part Description

The STM32H5F5J-DK is built around the STM32H5F5LJH7Q microcontroller, an Arm Cortex-M33-based MCU designed for modern embedded systems. The Cortex-M33 core supports Arm TrustZone technology, enabling hardware-assisted separation between secure and non-secure software functions.

The board includes a 4.3-inch touchscreen TFT LCD for graphical user interfaces, local controls, and visualization. Integrated connectivity and storage options include Ethernet, USB Type-C, and a microSD card interface. An M.2 Key E expansion connector allows designers to add compatible wireless or communication modules.

For sensing and interactive applications, the kit provides onboard motion sensing hardware. It also includes an STLINK-V3EC debugger and programmer, allowing firmware to be programmed, debugged, and evaluated without requiring a separate external debug probe.

The kit is compatible with STM32CubeH5 software tools and supports popular embedded development environments, making it suitable for prototyping, firmware development, demonstrations, and security-focused application evaluation.
