A gimbal is a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first animation). (From Wikipedia)
Thanks to Gimbals, you could take pictures and videos. Using PWM signal, Erle-Brain can command this device easily.
To connect the gimbal, needs three female-female wires.
Tilt: Connect one of your wire in T pin. Connect tilt to Erle-Brain channel 5.
Roll: Connect other wire in R pin. Connect tilt to Erle-Brain channel 6.
Ground: Connect one of the wire at ground "-", only one ground is needed.
Note: If you are using a Erle-HexaCopter you have to use the #7 and #8 pins in Erle-Brain 2
