About the Strawberry-Pi PCB

Strawberry-Pi is an open source STM32 PCB design by GoTouchGra55, published on GitHub. It is a 4-layer board measuring 85 × 57 mm, with 83 components from 38 distinct parts.

Its main chip is the STM32H743VITX, from the STM32 family. Other key parts include the LMR51430, TPS63070RNMR, LAN8742A and PCM1862DBT. By type, the board carries 40 capacitors, 19 resistors, 9 connectors, 5 ICs, 3 crystals and 3 inductors.

From the project

A Raspberry Pi-4 form factor STM32 development board designed as a compact computing platform.

A Raspberry Pi-4 form factor STM32 development board designed as a compact computing platform.

Strawberry Pi is a custom 4-layer STM32-based development platform built around the STM32H743 Cortex-M7 micro-controller.

The goal was to take the general concept of a small single-board computer and recreate it around a powerful micro-controller, integrating many useful interfaces and peripherals as possible into a compact Raspberry Pi 4 form factor.

Strawberry-Pi: common questions

What microcontroller does the Strawberry-Pi use?

The Strawberry-Pi is built around the STM32H743VITX, from the STM32 family.

How big is the Strawberry-Pi PCB?

The Strawberry-Pi measures 85 × 57 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Strawberry-Pi?

83 components, from 38 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 Strawberry-Pi design files?

From the GoTouchGra55/Strawberry-Pi 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 Strawberry-Pi design in my own project?

The repository has no license, so all rights stay with GoTouchGra55. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Strawberry-Pi 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.
