The Structure Sensor was designed to work with the Apple Lightning connector, so it will not work with iOS devices that have the older style 30-pin connector. The sensor uses the new Apple Lightning connector to transmit data at very high rates that were not achievable with the 30-pin connector.
The following iPads with the 30-pin connector are not supported:
- iPad (3rd Generation) -> [Models: A1416, A1430, A1403]
- iPad 2 -> [Models: A1395, A1396, A1397]
- iPad -> [Models: A1219, A1337]
