Pixhawk Lite – how can I use Servos?

ArduCopter Copter 3.3

A Pixhawk Lite has only 8 RC Out ports.
Is it possible to realize a camera Trigger via servo?
Can i configure one RC-OUT so that it should not use 400Hz?

A large Pixhawk would not fit in the frame.

Watch this video, it might help

Although it didn’t for me but that might be because of other issues.

Hello Paul.

My Pixhawk has no AUX Channel. Only 8x OUT.
For this he is smaller.
My looks like this:
