Optical Flow Sensor APM2.5 wiring to arduino mega 2560

Hi
I am trying to create a project but cant seem to find a wiring schematic for Optical Flow Sensor APM2.5 with the arduino mega 2560.

I keep finding the ones for Ardupilot mega but that is useless because it reffers to a shield not to the arduino .

this is what i could find Google Code Archive - Long-term storage for Google Code Project Hosting.

i am looking for a direct interface with the arduino mega .

Any help would be appreciated
Thanks in advance .

The megapilot and the 2560 use the same IC I think

Power, GND, NCS pins should be attached to A3
MISO, MOSI and SCLK pins should be directly soldered to the pins shown
Default mounting is lens pointing down, pins forward

so +5, GND, A3 (or any analog pins)

Digital pin 52 (SCK)
Digital pin 51 (MOSI)
Digital pin 50 (MISO)

Thank you for the reply .
The other pins i gather are not necessary ?

I will do that when i get home and post the result .
