The hardware designs within the Speeduino project are licensed under the TAPR open hardware license.

The TAPR Open Hardware License
Version 1.0 (May 25, 2007)
Copyright 2007 TAPR - http://www.tapr.org/OHL


Open Hardware is a thing - a physical artifact, either electrical or
mechanical - whose design information is available to, and usable by,
the public in a way that allows anyone to make, modify, distribute, and
use that thing.  In this preface, design information is called
"documentation" and things created from it are called "products."

The TAPR Open Hardware License ("OHL") agreement provides a legal
framework for Open Hardware projects.  It may be used for any kind of
product, be it a hammer or a computer motherboard, and is TAPR's
contribution to the community; anyone may use the OHL for their Open
Hardware project.

Like the GNU General Public License, the OHL is designed to guarantee
your freedom to share and to create.  It forbids anyone who receives
rights under the OHL to deny any other licensee those same rights to
copy, modify, and distribute documentation, and to make, use and
distribute products based on that documentation.

Unlike the GPL, the OHL is not primarily a copyright license.  While
copyright protects documentation from unauthorized copying, modification, 
and distribution, it has little to do with your right to make, distribute, 
or use a product based on that documentation.  For better or worse, patents 
play a significant role in those activities.  Although it does not prohibit 
anyone from patenting inventions embodied in an Open Hardware design, and 
of course cannot prevent a third party from enforcing their patent rights, 
those who benefit from an OHL design may not bring lawsuits claiming that
design infringes their patents or other intellectual property.

The OHL addresses unique issues involved in the creation of tangible,
physical things, but does not cover software, firmware, or code loaded
into programmable devices.  A copyright-oriented license such as the GPL
better suits these creations.

How can you use the OHL, or a design based upon it?  While the terms and
conditions below take precedence over this preamble, here is a summary:

*  You may modify the documentation and make products based upon it.

*  You may use products for any legal purpose without limitation.

*  You may distribute unmodified documentation, but you must include the
complete package as you received it.

*  You may distribute products you make to third parties, if you either
include the documentation on which the product is based, or make it
available without charge for at least three years to anyone who requests

*  You may distribute modified documentation or products based on it, if
    *  License your modifications under the OHL.
    *  Include those modifications, following the requirements stated
    *  Attempt to send the modified documentation by email to any of the
       developers who have provided their email address.  This is a good
       faith obligation - if the email fails, you need do nothing more
       and may go on with your distribution.

*  If you create a design that you want to license under the OHL, you
    *  Include this document in a file named LICENSE (with the appropriate
       extension) that is included in the documentation package.
    *  If the file format allows, include a notice like "Licensed under
       the TAPR Open Hardware License (www.tapr.org/OHL)" in each
       documentation file.  While not required, you should also include
       this notice on printed circuit board artwork and the product
       itself; if space is limited the notice can be shortened or
    *  Include a copyright notice in each file and on printed circuit
       board artwork.
    *  If you wish to be notified of modifications that others may make,
       include your email address in a file named "CONTRIB.TXT" or
       something similar.

*  Any time the OHL requires you to make documentation available to
others, you must include all the materials you received from the
upstream licensors.  In addition, if you have modified the
    *  You must identify the modifications in a text file (preferably
       named "CHANGES.TXT") that you include with the documentation. 
       That file must also include a statement like "These modifications
       are licensed under the TAPR Open Hardware License."
    *  You must include any new files you created, including any
       manufacturing files (such as Gerber files) you create in the
       course of making products.
    *  You must include both "before" and "after" versions of all files
       you modified.
    *  You may include files in proprietary formats, but you must also
       include open format versions (such as Gerber, ASCII, Postscript,
       or PDF) if your tools can create them.
