Adesso Wireless Mini Trackball Keyboard WKB-3100UB

The Adesso WKB-3100UB is a compact wireless mini keyboard with an integrated 800 DPI optical trackball that replaces a separate mouse for precise cursor control up to 30 feet away.

Designed for small workspaces, kiosks, home offices and mobile setups, this 87-key keyboard combines a built-in trackball and mouse buttons with reliable 2.4 GHz RF wireless connectivity. The plug-and-play USB receiver and compact 11.75-inch width make it easy to carry in a briefcase or tuck into tight desks. Durable membrane switches and an embedded numeric keypad deliver practical functionality for everyday computing across Windows systems.
