Hello!

I have finally decided to buy a Paparazzi autopilot.

I have the airframe. It is the Multiplex Funjet.


The following stuff have been ordered.

The Lisa board from JobyRobotics.com


From PPZUAV, Receiver board, Paparazzi GPS v1.3 Assembled LEA-5H, IR 
Sensors. 



Further I will need a Gumstix board. But what exactly do I need here to be 
able to connect it to the Lisa board and to the computer to program it? I 
might go for one with onboard WiFi. 

Where do I get the needed cables? I guess I need the following...
# An USB to autopilot cable,

# A cable from the receiver to the receiver board, and a cable from the 
receiver board to the autopilot. 
# Cables from the two IR sensors to the autopilot.
# Cable from the GPS to the autopilot.
# Cables from the servos and ESC to the autopilot.
# Cable from the Gumstix to the Lisa autopilot.
# Power cables to both the Lisa autopilot and to the Gumstix.

Anything else?

Do you intend to use 35/41/72Mhz radio control ? Are you sure you
don't want to patch into your rc receiver and avoid the multiple wires
to and from the decoder board ?
If you want to use 2.4Ghz radio control, the spektrum satelite
receiver plugs directly into one uart of the Lisa board. If you're a
futaba person, futaba has a 2.4Ghz rc receiver with a ppm output

Those are regular molex cables.

The gumstix plug directly into the 70 pins connector on the Lisa/l board

The gumstix is powered by the lisa board. The power connector on the
lisa board is regular jst ( known as BEC in the rc world )

looks good

Just a comment about wifi : I confirm that the internal adapter of the
overo doesn't work very well for me. I have had good success with a
linksys usb wifi key. Paul also added the driver to our filesystem for
this one

which comes with an antenna

I wasn't sure what I needed, so I just bought the board to be sure. I actually 
have both the Futaba receiver and a Spectrum satellite. The easiest would be to 
use the Spectrum satellite. But I think I have to change the Molex connector 
since it is a three pole connector. If I'm not mistaken, It need to be a four 
pole connector where three are used?

Yes I discovered that. But how do you access the Gumstix? Is an expansion board 
needed, or can you do it when it is connected to the Lisa/l board?

How do you connect it to the Lisa board?
