Development Boards & Kits - ARM Discovery kit with STM32H7B3LI MCU

Overview

The STM32H7B3I-DK Discovery kit is a complete demonstration and development platform for the STM32H7B3LIH6QU microcontroller. It features a 4.3-inch RGB interface LCD with a capacitive touch panel, making it an ideal choice for evaluating high-performance graphics and human-machine interface applications. The board includes 2 Mbytes of Flash memory and 1.4 Mbytes of RAM to support complex embedded software requirements.

Why Choose This Part

This kit integrates a high-speed 280 MHz ARM Cortex-M7 core with advanced power-saving modes and specialized graphics hardware acceleration. The inclusion of on-board Wi-Fi and Bluetooth modules, along with multiple expansion headers, provides extensive connectivity options right out of the box.

Applications

Human-Machine Interface (HMI)
Developing rich graphical user interfaces using the integrated Chrom-ART Accelerator and the 4.3-inch capacitive touch display.
Audio Processing
Leveraging the onboard stereo codec, digital microphones, and audio jacks for voice recognition or digital signal processing.
Industrial Control Terminals
Prototyping rugged monitoring systems using the integrated microSD card slot and various communication peripherals.
IoT Edge Gateways
Building connected devices that require local data visualization and high-speed processing at the edge.

Getting Started

Start development by downloading the STM32CubeH7 MCU Package, which includes numerous examples for the TouchGFX and STemWin graphics libraries. Connect the board via the integrated ST-LINK/V3E debugger to use IDEs such as STM32CubeIDE, Keil MDK-ARM, or IAR Embedded Workbench.
