Fun fact: #BitBox is NOT #OpenSource #hardware. Take a look at their git repos. You'll only find the firmware and apps. No electronics schematics there.

Prove me wrong. Reply with a link to a .kicad file that lets you build your own hardware.

OK, I'll admit that this is better than I realized, but I still don't see any files that would allow anyone to get a PCB made.
Nor do I see the original source files which would allow anyone to modify the PCB design and contribute back to the project.
Until I see this, I stand by my statement: BitBox is not open source hardware.
