The MMD KM21 Ultra Macropad Numpad is a compact, customizable input device designed for users who want more than just number entry. It suits power users, creatives, and macro enthusiasts needing a flexible pad with both keys and rotary controls. Its wireless and wired connectivity options make it adaptable for stationary or mobile setups. Users who value customization and multi-function control will find it useful, while those needing a full keyboard or extensive key count may find it limited.
The case is CNC-machined aluminum, offering a solid and stable base with a premium feel. It uses a top-mount structure with multi-layer damping materials to reduce noise and provide consistent keypress acoustics. This construction minimizes hollow sounds and key pinging common in cheaper pads.
Tri-mode connectivity supports USB-C wired, 2.4 GHz wireless via receiver, and Bluetooth 5.0. This flexibility allows low-latency wired use, near-latency-free wireless with the receiver, or multi-device Bluetooth connections. A 980 mAh battery supports extended wireless use, though exact battery life is unknown.
Compatible with Windows, macOS, Linux, and via Bluetooth also Android and iOS. The QMK/VIA firmware supports extensive remapping and macro creation, suitable for diverse workflows including gaming, office tasks, and creative software control.
