STMicroelectronics STM32H750B-DK

Overview

STM32H750B-DK from STMicroelectronics is a Discovery kit development board centered on the STM32H750XBH6 microcontroller - a single-core Arm® Cortex®-M7 MCU with 128 Kbytes of flash memory, 1 Mbyte of RAM, and TFBGA240+25 packaging. It integrates Ethernet (IEEE-802.3-2002 compliant, PoE-capable), USB OTG FS, dual CAN FD interfaces, SAI audio codec, MEMS digital microphone, 4-Gbyte eMMC, 128-Mbit SDRAM, and 4.3" RGB LCD with touch panel connector for embedded HMI prototyping.

For engineers reviewing the STM32H750B-DK datasheet, STM32H750B-DK pinout, STM32H750B-DK application, or STM32H750B-DK equivalent, this board serves as a production-ready reference platform for evaluating high-performance real-time control, industrial connectivity, and multimedia-rich edge applications - especially where dual-CAN FD, PoE-powered operation, and LCD-based UI validation are required.

Technical Context

The STM32H750B-DK implements a complete hardware reference design for the STM32H750XBH6 MCU, featuring full peripheral access including dual CAN FD controllers with ISO 11898-1 compliance, IEEE 802.3-compliant 10/100 Mbps Ethernet PHY with Power over Ethernet support, and SAI interface driving stereo audio output via headset jack and external speaker header.

It provides flexible power routing: 5 V can be sourced from RJ45 (PoE), ARDUINO® headers, USB Micro-B, or ST-LINK-V3E debug interface - enabling standalone or field-deployable evaluation. The on-board ST-LINK-V3E supports mass storage, Virtual COM port, and SWD/JTAG debugging without external tools.

FAQ

Does the STM32H750B-DK include an on-board debugger?

Yes - it integrates the ST-LINK-V3E debugger/programmer with full SWD/JTAG support, USB re-enumeration capability (mass storage, Virtual COM port, debug port), and no external hardware required for firmware flashing or real-time debugging of the STM32H750XBH6 MCU.

What display interfaces does the board support?

The board features a native 4.3" RGB parallel interface LCD with dedicated connector for capacitive multi-touch panels. It does not include HDMI or MIPI DSI; the RGB interface operates at up to 24-bit color depth and supports standard timing modes compatible with STM32H750XBH6's LTDC peripheral.

Can the STM32H750B-DK operate solely on Power over Ethernet?

Yes - the board accepts 5 V DC power directly from the RJ45 Ethernet connector when used with a compliant PoE injector or switch. This enables fully self-contained operation in networked edge deployments without additional power supplies or USB connections.

Is the STM32H750XBH6 on this board qualified for industrial temperature range?

Yes - the STM32H750XBH6 device mounted on the STM32H750B-DK is rated for –40 °C to +85 °C operation and conforms to industrial-grade qualification standards per STMicroelectronics' official datasheet (document DS12177, Rev 7).
