Request for STM32H745IIT6 Reference Design

Sakthi_IND · ‎2026-04-27

Dear Team,

We are planning to design a custom board based on STM32H745IIT6.
We would like to request whether STMicroelectronics can provide any official reference design (schematic, PCB files, or recommended evaluation board) specifically for STM32H745IIT6.

If there is no dedicated reference design for this exact part, please let us know:

Which existing STM32H745/H747 Discovery or Evaluation board can be safely used as the hardware reference for STM32H745IIT6
Any recommended documents or design guidelines to follow for production hardware

Kindly share the relevant links or document references.

Thank you for your support.

Regards,
Sathiya

See also the schematics, etc, for ST DK/Discovery/Nucelo etc boards ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
