CERN Open Hardware Licence
The CERN Open Hardware Licence (OHL or CERN OHL) is a licence 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[edit]
Contrary to most licence 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[edit]

On the CERN OHL website they have a list of projects using their licence.[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)
- ScopeFun open source oscilloscope[11]
- 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 licence.[12]
- 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[13]
- OpenScout an open source hardware mobile robot
Reception[edit]
The CERN OHL is an accepted free content licence according to the Free Cultural Works definition[14] and version 2 is approved by the Open Source Initiative.[15]
