Normally the due IO pins only can stand 3.3 V, but what about the I2C? Can i use the bus with 5V? i cannot find a good documentation about the I2c specification for the due.
i found this thread: http://arduino.cc/forum/index.php/topic,141237.0.html
but could not find out if it is possible without damaging the due.
sorry for this noob question but i soldered my hardware for 5 V and now it would be fine to operate the i2c bus at 5V.
