CERN Open Hardware License

CERN Open Hardware License ( OHL short ) is a license for the provision of free hardware that has been released from the nuclear research center CERN in March 2011. It is similar to the GNU General Public License and may be used by any interested user for their own projects free of charge. In July 2011, a revised version V1.1 of the OHL was published, which is fully compatible with its predecessor and includes minor changes and improvements.
