LMFAO did a kid draw that diagram? It shows nothing useful! The fact that they are using a picture mix with some block diagram drawn from microsoft words is super sketchy. If they're an engineering company, why are they not using CAD for their drawings?
Did you follow KNC when they first started? This is a startup, not a fully fledged corporation.
I'm an engineer, it doesn't take a full fledged corporation to mock up some real designs that are supposed to be getting ready for production. Since they are taking pre-orders, one would assume that they would already move past something that takes less than 20 minutes draw a grossly simplify mock up on how the components are going to be laid out.
They actually put together a road map, and a mockup of the hardware components. You can find that on their website.
