Arduino micro as i2c slave

Hi all,

I'm trying to connect an Arduino micro to the Pixhawk through the i2c port.
Actually it doesn't works, I think it depends on voltage levels of the i2c bus.

The Pixhawk connections are shown on the following link:
http://ardupilot.org/copter/docs/common-pixhawk-overview.html

for simplicity I transcribe them here:

1 VCC +5V
2 SCL +3.3V (pullups)
3 SDA +3.3V (pullups)
4 GND GND

How can I correctly connect it?

Every advice would be very appreciated,

Thank you.
