The era of open voice assistants

It's not clear to me from the description if this is also completely open source hardware. Are the schematics, BoM, firmware published under a permissible license? If so, where are they accessible?

And if not, I would be curious to know why it haven't been fully open sourced.

I would think so in the end. They talked about the case design being open. The software and firmware are all open already and they said that they really wanted people to be able to take these components and make new devices.

They have relesased the designs for the yellow so I assume it will all come. https://github.com/NabuCasa/yellow
