Open Hardware Licence text not on schematics, nor on PCB
Check that each schematics page has on the same place the Open Hardware Licence text of its corresponding variant (-S, -W, -P): "Copyright mycompany 2020. This source describes Open Hardware and is licensed under the CERN-OHL-S v2 ..."
-
This text can be found in the corresponding 'Guide' at CERN OHL version 2.
-
Check for this same OHL text on the mechanical drawings (front-panel and 'arrangement').
