The OpenXC Platform

OpenXC™ is a combination of open source hardware and software that lets you extend your vehicle with custom applications and pluggable modules. It uses standard, well-known tools to open up a wealth of data from the vehicle to developers, even beyond OBD-II.

What is OpenXC™?

OpenXC™ is an open source, data-focused API for your car. By installing a small hardware module, the vehicle data becomes accessible to Android or other desktop applications using the OpenXC library.

OpenXC Overview

Unlocking Rich Vehicle Data

OpenXC™ allows consumer devices, such as smart phones, to access data from any vehicle. Using OpenXC™, you can monitor many of the sensors on a vehicle, enabling new and innovative vehicle-centric applications. Some data is required by law and more can be unlocked with support from an automaker - or a little reverse engineering effort!
