Custom Mechanical Number Pad MF34 QMK/VIA Programmable Numpad - Hot

In this review of the Custom Mechanical Number Pad MF34, the bottom line is simple: this is a programmable, hot swappable 34-key numpad built for power users who want a tactile, configurable adjunct to a laptop or compact keyboard. It is most appealing to people who value full programmability via QMK and VIA and who want a smoother typing feel from pre-lubed linear switches. The MF34's combination of a full 34-key layout, RGB backlighting, and multilayer sound damping makes it a strong choice for data entry, spreadsheet work, or as a flexible macropad.

Key Features

• QMK/VIA customization: Open-source firmware lets users remap each key, create multiple layers and custom shortcuts to speed workflows and support macropad-style setups.
• Wired 34-key layout: A full set of numbers, function and navigation keys increases productivity for numeric tasks without losing essential navigation controls.
• Hot swappable switches: The pre-lubed Bsun linear switches offer a smooth, creamy feel and can be swapped without soldering to customize typing characteristics.
• PBT dye-sub keycaps: Durable keycaps resist wear and retain legends while complementing the RGB backlight for a clean, long-lasting appearance.
• Multi-layer silencing structure: Poron, sandwich foam and IXPE switch pad reduce ping and make typing sound more pleasant for desktop use.
• RGB backlit effects: Multiple lighting modes let the numpad visually integrate with most keyboards and provide usable illumination in low light.

Who It's For

The MF34 is aimed at mechanical keyboard enthusiasts, spreadsheet professionals, and content creators who want a dedicated, programmable numeric pad with comfortable linear switches and advanced firmware control. Users who already use compact keyboards or laptops and need a separate numeric input device that doubles as a macropad will find the MF34 particularly useful.

It is less suitable for users who have extremely limited desk space or who only need a minimalist numeric input; compared with smaller 17-key numpads the MF34 is larger (5.87' x 5.28' x 1.54' in) and will occupy more desktop area. Buyers who require wireless connectivity should also look elsewhere, as this is a wired USB device.

Pros & Cons

Pros

• Full programmability with QMK/VIA enables extensive customization and multiple layers for complex macros.
• Hot swappable pre-lubed linear switches deliver a smooth, comfortable typing experience out of the box.
• Durable PBT dye-sub keycaps and attractive RGB lighting improve longevity and aesthetics.
• Multi-layer silencing structure produces a refined acoustic profile during use.

Cons

• At 34 keys and the listed dimensions, it takes more desktop space than smaller numpad alternatives.
• Wired connection may not suit users who prefer a wireless peripheral.
