Meletrix ZoomPad Numpad

The Meletrix ZoomPad is a compact 20-key mechanical keyboard suited for users who want a small, versatile input device with multiple connection options. It fits hobbyists who frequently swap switches, and users needing Bluetooth, 2.4GHz wireless, and wired modes in one keyboard. Its gasket mount and aluminum case offer a balance of durability and typing comfort.

Key Features

• Tri-mode connectivity supports wired, Bluetooth 5.2, and 2.4GHz wireless, allowing seamless switching between up to three devices.
• Hot-swappable PCB supports both 3-pin and 5-pin switches, enabling easy customization without soldering.
• RGB lighting is available on select models, with options for nightlight knobs and customizable backplates for personalization.
• Includes a Li-ion battery for wireless use, though exact battery life is unknown.

Build Quality

• Aluminum top and bottom case with anodized electrostatic coating provides a sturdy and scratch-resistant shell.
• Gasket mount design offers a softer typing feel by isolating the plate from the case, reducing vibrations.
• Includes stabilizers and Poron foam dampeners to improve acoustics and reduce noise.
• Some assembly challenges reported, such as tight stabilizer inserts and loose screen fit, which may affect long-term durability.

Typing Experience

• Gasket mount and foam dampeners contribute to a quieter and more cushioned typing sound.
• Stiff rotary knob may prevent accidental scrolling but could feel less smooth for some users.
• Switch customization through hot-swap supports a wide range of tactile preferences.

Connectivity and Compatibility

• Supports Windows, Mac, iOS, and Android systems, making it versatile across devices.
• Bluetooth 5.2 allows pairing with up to three devices for easy multitasking.
• Polling rates vary by mode: 125Hz for Bluetooth, 1000Hz for wired and 2.4GHz wireless, suitable for general use but may not meet competitive gaming needs.
• Firmware support includes VIA for tri-mode PCB and QMK/VIA for wired PCB, enabling advanced key remapping.

Trade-offs

• Small 20-key layout limits use to specific workflows or as a supplementary device rather than a full keyboard replacement.
• Assembly can be challenging, especially stabilizer installation and securing components, which may deter less experienced builders.
• Some minor fit issues like screen rattle and stiff rotary knob may affect user experience.
• Battery life details are not provided, so wireless endurance is uncertain.
