Licensing

We feel strongly that our users deserve the full freedom to learn from, exploit, and extend the hardware and software tools that we provide. To a lesser extent we also believe that anybody should have the freedom to adopt, reuse, or imitate these tools for any purpose without having to worry about licensing conflicts. Acting on these beliefs we have selected the most permissive licenses possible for our software tools (while respecting the licenses of software projects we have directly branched from) and have released our hardware designs (including the raw  gerber blueprints rendered for manufacturing) under a slightly more conservative share-a-like license.

Much ink has been spilt on the subject of Free and Open Source Software and Hardware; appropriately enough Wikipedia is a great place to get some context (see Open SourceOpen Source HardwareCopyleft, etc). We would like to thank the Free Software Foundation, the Electronic Frontier FoundationCreative Commons, and many others for legally enabling our business model.

Acknowledgements

Our devices and software would not be feasible without decades of generous effort by hackers from around the world. Some of the projects we directly build off of are:

  • The Arduino development board and programming environment, which in turn inherits from Wiring and Processing
  • The OpenMoko project’s dfu-util USB firmware flashing utility
  • The GCC compiler and the rest of the GNU toolchain
  • Modifications to the arm-none-eabi GCC target by Codesourcery, Inc
  • The Kicad circuit layout software suite

We would also like to credit a few projects we find inspirational: ladyadaelphel, sparkfun, and of course arduino.
