A low cost, DIY friendly Engine Management System (ECU) based on the Arduino framework
Speeduino
The Speeduino project is a flexible, fully featured Engine Management Systems (EMS aka ECU) based on the low cost and open source Arduino platform. It provides the hardware, firmware and software components that make up an engine management system, all provided under open licenses. With over 1000 installations, Speeduino has matured into a product that meets the needs of the hobbyist and enthusiast community without driving prices to the levels of traditional aftermarket ECUs.
Overview
This repositiory contains the official Speeduino hardware designs. All new designs have been made in Kicad, with some early boards developed in Fritzing.
License
These designs are release under the CERN Open Hardware License v2 Strong (CERN-OHL-S). This license is similar to the GPL, however is designed specifically for hardware design files, including PCB layouts and schematics. As the 'strongly reciprocal' version of the CERN OHL is used, you may use, copy, modify and create variations of these designs freely, provided that any changes or variations are also released under this CERN-OHL-S.
Where to Buy
Pre-made Speeduino units/boards are available from a number of official resellers
These resellers all contribute a portion of sales back to the project to allow for continued development to take place and we encourage sales through them whenever possible.
Of course, being open source, you are free to use the design files provided here to create your own hardware!
Support
In addition the manual referenced above, Speeduino has a large and very vibrant community of people to help out with your setup or any questions you might add.

Questions
How big is the V0.4.4d PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V0.4.4d use?
297 parts, built around the IXDN602PI, MPX4250A, VNLD5090TR-E and SSM3K357R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the V0.4.4d KiCad files?
From the speeduino/Hardware repository on GitHub, at the commit this page was made from: the board is v0.4/SMD/Latest/v0.4.4d.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the V0.4.4d design in my own project?
Its repository states no licence, so its author keeps all rights: ask speeduino before reusing the design.
