CERN Open Hardware Licence

The CERN Open Hardware Licence (OHL or CERN OHL) is a license used in open-source hardware projects. It was created by CERN, which published version 1.0 in March 2011. Version 1.1 was published in July 2011.^[1] Version 1.2^[2] was published in September 2013.^[3] Version 2.0,^[4] which utilizes a simplified language and covers also integrated circuit designs,^[5] was published in March 2020.^[6]

Wording[]

Contrary to most of license names, the CERN OHL uses the British English spelling licence rather than the American English spelling license which contains an "s".

Projects using the CERN OHL[]

The ColorHug2, an open source colorimeter.

On the CERN OHL website they have a list of projects using their license.^[7] These projects include:

Most projects in the Open Hardware Repository OHR
AXIOM^[8] – digital cinema camera
Gizmo For You Ltd
Mechanical Ventilator Milano^[9] Rapid production ventilator design as an answer to COVID-19 shortage
The Monero Hardware Wallet^[10] The first (licensed schematic and layout) Monero hardware wallet
Mycroft Mark I – smart speaker with open-source digital assistant (design files available here)
SimpleMachines
SatNOGS-the open satellite ground station network
The synchrotron instrumentation PandAbox which chorographs experiments at particle accelerator and other facilities
Tinkerforge Bricks and Bricklets
The tristimulus colorimeter Colorhug2 Archived 2017-03-12 at the Wayback Machine uses version 1.1 of this license.^[11]
UPSat-the first open hardware satellite 1
A Free Beer variation, brewed for the RMLL 2012 and recipe placed under the CERN OHL 1.1^[12]

Reception[]

The CERN OHL is an accepted free content license according to the Free Cultural Works definition^[13] and version 2 is approved by the Open Source Initiative.^[14]
