Structure Sensor attaches to the 2nd and 1st generation 12.9-inch iPad Pro with a different kind of bracket than other models. It attaches with removable, residue-free adhesive pads (see below for instructions) to ensure a precise, low profile fit. It also comes with a new, longer, Lightning connector cable which supports the 2nd and 1st generation 12.9-inch iPad Pro's larger size.
1. On the back of the Bracket, peel the backing off from all three adhesive pad pieces as shown.
2. Align Bracket with the Alignment tool, slowly press the Bracket completely down on top of the iPad Pro.
This can make using Structure Sensor with the 2nd and 1st generation 12.9-inch iPad Pro less convenient if you are intending to take it on and off repeatedly, as you will have to either leave the sensor mount on or re-align it each time. If the iPad is primarily for 3D scanning, or if you don't mind leaving it on, then it should make no difference at all!
