Touch accuracy is rated at 1 mm, and the kit connects to a host computer over a USB 2.0 interface, drawing its power from that USB connection.

It does not include IWB software, and its package contains the manual and installation accessories. It suits classrooms, meeting rooms and signage installations that need touch on a 49-inch screen, and it works with Windows, macOS, Android and Linux hosts over USB.
