Hello! I have a external device (communicating with TTL level signals) which is working well with Arduino Mega 2560 R3 through digital IO pins of Mega, now if I try out Arduino Due with this device which writes 4, 82 volts (measured from pin) to Arduino input pin, is there a risk of damage , does…

Hi , i'm new with arduino but i saw that the newest versionf of the shields have an IOref pin, so maybe they can adapt to the due...
