Full-size 104-key gaming combo

The usbroway RK400 bundles a full-size 104-key wired keyboard with an ergonomic mouse. The keyboard uses a standard layout including function keys for efficient typing at work or while gaming. A detachable wrist rest and stepped keycap profile reduce hand fatigue during long sessions. Both devices connect by USB with no driver installation required.

Upgrading from membrane or compact boards

Users moving from a compact or membrane keyboard gain a full complement of keys and adjustable RGB backlighting with three modes and multiple brightness levels. The mouse adds four selectable DPI steps at 1200, 1600, 2400 and 3200 for different sensitivity needs. The jump is worthwhile when you want dedicated media controls, a numeric keypad and per-key illumination without software configuration.

Check your ports and OS before ordering

The combo needs two free USB-A ports on the host machine. Compatibility is listed for Windows XP through Windows 10 and Mac OS, so verify your operating system version matches. No additional power adapter or proprietary software is required, but ensure the keyboard’s wired cable length suits your desk layout.

Questions about this item

What desk space does the RK400 with its integrated wrist rest need?

The full-size 104-key keyboard includes a built-in wrist rest that extends the front edge, so measure your desk depth to accommodate the extra length.

How do I set the mouse to 3200 DPI and make it stay after reboot?

Press the DPI button on the mouse to cycle through 1200, 1600, 2400 and 3200; the last selected level is stored in the mouse itself and survives a restart.

When should I replace the ABS keycaps or the mouse feet?

ABS keycaps develop shine from finger oils over months of heavy use; mouse feet wear down when glide feels rough — replace either part when performance drops.
