hi! i accidently set 12v on arduino mega 5v output pin. board still works and runs my program, but i'am not able to load any new sketches to it. TX / RX lights dont response and arduino IDE says timedout() etc.. when try to load new sketch in it. i think there's nothing else to do that buy new one…

arduino mega got 12v in 5v output pin
