About the STM32H755ZI breakout board

STM32H755ZI breakout board is an open source STM32 PCB design by LiU-SeeGoals, published on GitHub. It is a 4-layer board measuring 70 × 95 mm, with 38 components from 12 distinct parts.

Its main chip is the STM32H755ZITX, from the STM32 family. Other key parts include the ST1L05CPU33R. By type, the board carries 31 capacitors, 3 resistors, 2 ICs, 1 switch and 1 diode.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Schematics etc.

Motor driver has 5 pins to the devboard, 2 power pins and 8 pins to the motor

Capacitors and components change capacitance, inductance, etc as the voltage changes. This was not know during the making of driver.

Capacitors should be closer to the pins they are filtering.

There is a risk of overheating if the motors get stuck for a longer time, adding some cooling would be nice.

STM32H755ZI breakout board: common questions

What microcontroller does the STM32H755ZI breakout board use?

The STM32H755ZI breakout board is built around the STM32H755ZITX, from the STM32 family.

How big is the STM32H755ZI breakout board?

The STM32H755ZI breakout board measures 70 × 95 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the STM32H755ZI breakout board?

38 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the STM32H755ZI breakout board design files?

From the LiU-SeeGoals/Electronics repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the STM32H755ZI breakout board design in my own project?

The repository has no license, so all rights stay with LiU-SeeGoals. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32H755ZI breakout 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.
