Can I use a Windows 8 Pro Tablet that only has a Micro USB connector (as opposed to a full USB)?
Yes, with some restrictions. As long as the Micro USB connector on the tablet is made for Data Transfer as well as for charging, it will work together with the PCEye Go and the EyeMobile. In this case you will need to use an adapter to make it work. You can use an off the shelf Micro USB (male) to USB (female) OTG Adapter to connect between the PCEye Gos USB and the tablets Micro USB.
The tablet must, of course, also fulfill the other requirements mentioned in the technical specifications and above.
