    It is possible to connect the Arduino UNO and UDOO with a network through I2C using the SDA and SCL pins? Would there be any harm if I call them directly? For example http://arduino.cc/en/Tutorial/MasterReader, this direct communication does not exceed the 3.3v I/O UDOO? It would be necessary to use resistors?
