The Gumstix is already placed on the Lisa/L board. So, adding an expansion board is not possible.

Maybe the best solution is a USB capture card connected between the camera and the Lisa/L / Gumstix board. Then there are a lot of cameras to choose from.

What cameras would be recommended? The ultimate solution would be a camera with zoom and the possibility to configure in flight.

The camera below has a remote that enables it to be configured. Not sure if this can be adapted to be done remotely or automatically with software.

The camera will, at the moment, only be used to capture in flight video. So maybe a cheaper, and simpler solution would be better.

Hello!

I was just wondering what type of camera that was in use. It seems like
the ones in the Wiki. all uses an analog connection cable.

I guess this does not get connected to the autopilot, but to the radio
transmitter directly.

I'm building an UAV based on the Lisa/L board and a Gumstix board. And I
would like to connect a camera to the Lisa/L board.

The Gumstix Overo CPU has a camera interface. Several solutions exist for
that. The pins might be tricky to reach, since Overo AFAIK does not route
them in the 'big bus'.

USB might be a bit too low-tech. Webcams generally have awful frame rates.
