CARGB Firmware Licence
The terms the firmware on a CARGB controller is used under. Updates are included for the life of the device, no feature is withheld in software, and the licence transfers with the device when you sell it.
The same text the controller shows under Device Info, and the same LICENCE.md shipped in every release package. The simulator on this site runs in a browser rather than on a controller, so it has its own CARGB Simulator Licence. Open-source components are listed in the third-party notices.
