Compact wireless keyboard with built-in trackball

The Adesso WKB-3100UB combines an 87-key layout and an integrated optical trackball in a single unit measuring 1.00" x 11.75" x 6.00". It connects through a 2.4 GHz RF link using a USB receiver and offers 65000 IDs across 12 channels for a 30-foot range. The device weighs approximately 1.07 lb and operates on Windows 2000 through Windows 8.

Suited for tight workspaces needing combined input

This keyboard fits users who want cursor control without a separate mouse surface, such as living-room PCs, kiosks or server racks. The trackball operates at 800 DPI with optical tracking. Buyers who need a dedicated numeric keypad, multi-device pairing or support for operating systems beyond Windows 8 should consider other options.

RF wireless link with 30-foot range

The single specification that decides compatibility is the 2.4 GHz RF interface requiring an available USB port for the supplied mini receiver. No alternative wired or Bluetooth connection is provided. If the host lacks a free USB-A port or the environment demands a different wireless protocol, this unit will not integrate.

Questions about this item

Will the 2.4 GHz RF receiver conflict with my older USB keyboard if both are plugged in?

Each receiver uses one of 65000 IDs across 12 channels so the WKB-3100UB pairs only with its own dongle; the second keyboard keeps its own receiver and both work independently.

How can I verify the built-in optical trackball is tracking at the specified 800 DPI after setup?

Move the ball and check pointer speed in Windows mouse settings; the cursor should travel the same distance per ball rotation as any other 800 DPI device on the same surface.

Does the box include the mini receiver and its holder, or must I buy them separately?

The package contains the WKB-3100UB keyboard with integrated trackball, the 2.4 GHz USB mini receiver, and a dedicated receiver holder — no extra purchase needed.
