About the RT-STACK PCB

RT-STACK is an open source STM32 PCB design by fupsrl, published on GitHub under the CC-BY-NC-4.0 license. It is a 6-layer board measuring 150 × 150 mm, with 472 components from 71 distinct parts.

Its main chip is the STM32G474VETX, from the STM32 family. Other key parts include the IFX007TAUMA1, SN74AHC1G02DCKR, SN74AHC1G08DCKR, IR2101 and ACS722xLCTR-20AB. By type, the board carries 173 resistors, 124 capacitors, 67 ICs, 56 diodes, 36 transistors and 12 connectors.

From the project

V12 GDI ready real time ECU stack

RT-STACK is an open-source, real-time engine-control platform for experimental, motorsport, and bench-development applications. It combines a deterministic STM32G4 real-time controller with the option to add a Raspberry Pi or another high-level computer for advanced control, data handling, and calibration workflows.

The hardware is deliberately ambitious—twelve injector channels, twelve ignition channels, trigger inputs, lambda interfaces, CAN, and a standard ECU connector—while the checked-in firmware is a transparent, configurable reference implementation. Start on the bench, understand…

RT-STACK: common questions

What microcontroller does the RT-STACK use?

The RT-STACK is built around the STM32G474VETX, from the STM32 family.

How big is the RT-STACK PCB?

The RT-STACK measures 150 × 150 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the RT-STACK?

472 components, from 71 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 RT-STACK design files?

From the fupsrl/RT-STACK 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 RT-STACK design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the RT-STACK 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.
