Ergonomic Wave Keyboard & Mouse Combo

The Keychron MA31 pairs a full-size wave-shaped keyboard with a cushioned palm rest and a sculpted mouse in one 2.4 GHz wireless set. A single USB-A and USB-C receiver connects both peripherals up to 33 ft away. The keyboard is rated for 10 million keystrokes and the mouse offers three DPI settings at 800, 1200 and 1600. It runs on batteries and works with Windows, macOS, tablets and laptops.

Suited For Desk Workers Needing One Unified Set

This combo suits users who want a single receiver for both keyboard and mouse without Bluetooth pairing steps. The fixed wave layout and integrated palm rest help typists who prefer a contoured key shape. Buyers who need multi-device switching, a compact layout or wired connectivity should look elsewhere. The keyboard and mouse connect to only one host at a time.

Build Integration With USB-A & C Dongle

Plug the included receiver into any USB-A or USB-C port and both devices are active immediately with no driver install. The 2 mm thick keyboard measures 16.5 x 9.15 x 1.89 inches and weighs 1.27 kg, fitting standard desk space. Battery power removes the need for charging cables. FN+Q and FN+W toggle the key mapping between Windows and macOS layouts.

Questions about this item

Does the 2.4 GHz USB-A/C receiver require a free USB port on my computer?

Yes, one 2.4 GHz USB receiver plugs into a USB-A or USB-C port and links both keyboard and mouse with a 33 ft range.

Will the keyboard and mouse work if I keep my older wired keyboard plugged in at the same time?

The combo connects to one device at a time; the older keyboard can stay attached but the MA31 will only control the machine paired to its receiver.

How can I confirm the 3 DPI levels on the mouse are active after setup?

Press the mouse DPI button to cycle through 800, 1200 and 1600 settings; the cursor speed changes immediately at each level.
