The hardware must be released with documentation including design files, and must allow modification and distribution of the design files. Where documentation is not furnished with the physical product, there must be a well-publicized means of obtaining this documentation for no more than a reasonable reproduction cost, preferably downloading via the Internet without charge. The documentation must include design files in the preferred format for making changes, for example the native file format of a CAD program. Deliberately obfuscated design files are not allowed. Intermediate forms analogous to compiled computer code -- such as printer-ready copper artwork from a CAD program -- are not allowed as substitutes. | The hardware must be released with documentation including design files, and must allow modification and distribution of the design files.

The documentation for the hardware must clearly specify what portion of the design, if not all, is being released under the license. | The documentation for the hardware must clearly specify what portion of the design, if not all, is being released under the license. The license may restrict the bill of materials to components which are generic, open-source, or otherwise non-proprietary. Alternatively, the design may incorporate the use of non-open components, for example if a manufacturer releases the design for a development board that incorporates a proprietary integrated circuit. The license may not require that any specific components, goods or services be used. | ||

a) The interfaces are sufficiently documented such that it could reasonably be considered straightforward to write open source software that allows the device to operate properly and fulfill its essential functions. For example, this may include the use of detailed signal timing diagrams or pseudocode to clearly illustrate the interface in operation. | a) The interfaces are sufficiently documented such that it could reasonably be considered straightforward to write open source software that allows the device to operate properly and fulfill its essential functions.
