OpenH743I-C Standard, STM32H7 Development Board

OpenH743I-C Standard — Modular and Typical STM32H7 Development Board
A powerful and professional development board featuring the STM32H743IIT6 controller with a 480MHz Cortex‑M7 processor, 2MB Flash and 1MB RAM. The modular design allows for easy connection to expansion modules such as LCD screens, cameras, USB HS communication, Ethernet, Arduino and more. Ideal for STM32-based projects that require flexibility, performance and rich connectivity.

OpenH743I-C Standard includes two main components: the motherboard and the CoreH743I core board. The core uses the STM32H743IIT6 microcontroller (32-bit RISC with Chrom-ART graphics FPU) at a frequency of 480 MHz, with internal memories of 2 MB Flash and 1 MB RAM.

The board was designed with an open modular approach, with a wide range of interfaces:

Connection to the CoreH743I board

Arduino interfaces (connectors and ICSP)

Camera connection via DCMI

8-bit FMC interface (for NAND Flash and more)

ULPI for USB HS connection (USB HS controller built into STM32)

A pair of LCD interfaces for displays up to 10.1″

SAI1 for connecting audio modules, SPI, I²C, UART, USART, CAN, Ethernet and more

The board also includes:

Power connections (5V DC or USB), supply switch, 5V/3.3V pins

CP2102 (USB-to-UART), status LEDs (Power, USB), joystick, Wake/Reset buttons, jumpers for custom-configuring I/Os

The board also supports debug options such as JTAG/SWD and IAP, including design for flexibility such as BOOT‑mode, VREF, VBAT, OTG jumpers and more. Proximity to RTC circuits, regulated power supply, and built-in power managers enable reliable and widespread use

What makes OpenH743I‑C unique is the modular and open design approach that emulates the principles of engineering software: openness, modularity, extensibility, and ease of use — making it a powerful and flexible platform for developing embedded systems based on the STM32 family
