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!
