YUNZII IF99 (QMK/VIA)

YUNZII IF99 — Full-Size Wireless Mechanical Keyboard with LCD Screen

The IF99 is a prebuilt 95% (full-size with numpad) mechanical keyboard that packs a customizable LCD screen, QMK/VIA programmability, tri-mode wireless connectivity and a gasket-mounted, sound-dampened build into one ready-to-use board. This configuration comes in Black with Gateron Zero linear switches.

Please note: This product ships fully assembled with Gateron Zero linear switches and double-shot PBT Cherry profile keycaps installed — ready to type out of the box. Looking to build your own? The IF99 is also available separately as a barebone kit (no switches or keycaps).

Personalize It — Custom LCD Display

• Customizable LCD Screen: Display the time, GIFs, photos, battery status, connection mode and more — add your own images to make the board truly yours.
• Magnetic Metal Badge: A colourful, removable magnetic badge adds a premium touch and doubles as a hidden storage spot for the 2.4GHz receiver.
• South-Facing RGB: 16.8 million colours with multiple lighting effects, plus an LOGO LED — south-facing LEDs keep lighting even and avoid interference with Cherry profile keycaps.

Make It Yours — QMK/VIA & Hot-Swap

• QMK/VIA Support: Remap keys, build macros, create shortcuts and tune RGB effects on Windows and macOS with open-source QMK/VIA.
• Hot-Swappable PCB: Every key is hot-swappable and accepts both 3-pin and 5-pin MX-style switches — no soldering required.
• Gasket Mount: A gasket-mounted structure with multiple layers of sound-absorbing material delivers a softer, creamier typing feel and sound.

Built for Work & Play — Tri-Mode & Long Battery

• Tri-Mode Connection: Wired USB-C, Bluetooth 5.0 and 2.4GHz wireless — connect up to 5 devices including PCs, laptops, tablets and phones.
• 8000mAh Battery: A high-capacity battery keeps you going for long sessions between charges.
• 1000Hz Polling Rate & NKRO: Responsive, reliable input with full N-key rollover for gaming and fast typing.
