I have a genuine Uno which I've just replaced the Atmega328PU chip on.
I now have it programmed with GRBL and have GRBL's settings just how I want them.
Is it possible to clone the Atmega328PU on the Uno to a blank Atmega328PU chip so I have 2 the same?
If so, what's the easiest way to do it?
Just wondered because I'd like to have a spare which I can just plug in if needed.
