So even after I wrote myself a note to use 5volts on my new U3S, I got excited and cooked it with 12v !!
I know the ATMega is cooked, but wondering if everything else may be OK...I hope the 3.3 voltage regulator saved the Si5351A, and I checked out the LCD and it survived.
Questions:
1.  What else may be a gonner?
2.  I have a spare ATMega from a QCX.  Can I reflash it for the U3S or are the code plugs different?

At least I have plenty of snow to shovel to keep me busy if I have to order parts!
