Hi,
The two versions differ by some of the hardware components. You can tell the difference by sight – 1.0 device has a temperature sensor in the optical head whereas 1.1 device has only one sensor, the illumination source.
The external temperature sensor does not perform well enough to use it for model creation – therefore it has been removed.
We have shipped SCiO v1.0 to developers. Currently, we only ship v1.1 devices.
