The Zenmuse X5 Vibration Absorbing Board is included in the Inspire 1 Pro kit. It is not included with the Zenmuse X5 kit and needs to be purchased separately.

When using the Zenmuse X5 Series cameras, it is necessary to replace the original vibration absorbing board designed for the Inspire 1’s standard Zenmuse X3 camera.
The Inspire 1 Pro Vibration Absorbing Board is made from shock-resistant magnalium which effectively absorbs vibrations.
