Thanks for the update - that's good to know!
I could be wrong here, but VCC can mean 3.3v or 5v (or a bunch of other stuff) - it's just the voltage the system runs at. But yeah, if the 3.3v wires have 5v on them, that's extremely scary!
Honestly, I'm pretty impressed the Puck took that - I guess maybe the 5v regulator isn't that powerful so maybe with the increased power draw the voltage dropped to something less destructive!
