hi guys. hope all is well.
lets say i build a circuit using raspberry pie and then sell it. lets say i made about $230000 selling it. now can raspberry pie ask for a chunk of that money?
Do i need to inform raspberry pie that i am using their device? do i need permission to use their device in my product and sell it?

thanks

 

No

But you should read their licensing information anyways..
Some here..
and I'm sure if you spent a few minutes on google you could find more..

I prefer peach pie myself.
