It is not a drop-in replacement. It would be a mistake to put 5V on any of the pins, although the internal regulator can handle it. Also, even something as simple as printing "Hello World" is a little different:
void setup(){
  SerialUSB.begin(9600);
  while(!SerialUSB){
    ;
  }
}

void loop(){
  SerialUSB.print("Hello World");

Note the use of the SerialUSB object instead of just Serial. Also, like the Arduino Due and Zero, you need a "while spin" for the COM link to establish itself. Most things are the same, but you should expect a few gotchas along the way.

I checked the pin-out and looks like SDA and SCL are different?

I also wonder if being 3volt rather than 5volt chip is a problem?


Correct me if I am wrong.
