About the STM32H7 Board

STM32H7 Board is an open source STM32 PCB design by phancak, published on GitHub under the MIT license. It is a 4-layer board measuring 100 × 50 mm, with 102 components from 46 distinct parts.

Its main chip is the STM32H7S3I8T6, from the STM32 family. Other key parts include the MT29F1G08ABAEAWP-IT:E TR, SN74LVC1G07DBVR and USBLC6-2SC6. By type, the board carries 47 capacitors, 32 resistors, 5 ICs, 4 connectors, 3 inductors and 2 crystals.

It belongs with the audio and displays & leds designs in this gallery.

From the project

High-Performance STM32H7S3 System-on-Module | 600MHz ARM Cortex-M7 | External SDRAM & NAND Flash Integration | 4-Layer High-Speed PCB optimized for real-time control and LCD UI.

The platform is designed to serve as a high-bandwidth "Main Compute Module" that interfaces with expansion boards via a variety of industrial-standard protocols (PSSI, I2S, I2C, SPI, UART).

To ensure the reliability of a 600 MHz system, the following hardware validation protocols were implemented:

STM32H7 Board: common questions

What microcontroller does the STM32H7 Board use?

The STM32H7 Board is built around the STM32H7S3I8T6, from the STM32 family.

How big is the STM32H7 Board?

The STM32H7 Board measures 100 × 50 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the STM32H7 Board?

102 components, from 46 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM32H7 Board design files?

From the phancak/STM32H7_Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the STM32H7 Board design in my own project?

Yes, under the terms of its MIT license, which phancak chose for the repository.

Can I test firmware for the STM32H7 Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
