YUNZII B75 PRO MAX QMK/VIA Knob TFT Screen Wireless Mechanical Keyboard
This YUNZII B75 PRO MAX is a feature-packed 75% custom mechanical keyboard built for enthusiasts and daily users alike. Adopting the popular Gasket mount structure, it delivers soft, quiet and satisfying typing feedback, far smoother than traditional plate-mounted keyboards. It supports tri-mode connectivity: 2.4G wireless, Bluetooth and wired, so you can seamlessly switch between multiple devices such as laptops, desktops and tablets. Equipped with a large 8000mAh built-in battery, it brings extremely long battery life for all-day use. The integrated rotary knob and customizable TFT color screen set it apart from most regular 75% keyboards; you can adjust settings and personalize the screen content via web customization. Full-key hot-swappable sockets accept both 3-pin and 5-pin switches, letting you freely tweak your typing feel without soldering. It comes with premium double-shot PBT OEM keycaps that resist shine and wear after long hours of use. It is fully programmable with QMK and VIA, and compatible with Windows, Mac, Linux, Android and iOS systems, fitting gaming, office work and creative scenarios perfectly.
Most common 75% keyboards only offer basic lighting and simple remapping. This model stands out with its handy TFT display and control knob for quick adjustments. The huge 8000mAh battery beats many competitors on battery endurance. Combined with Gasket damping, full hot-swappability and QMK/VIA support, it balances great typing feel, strong customization and multi-device convenience in one package.
