K4H-F1 specification sheet

Overview:

The Keychron K4 HE Wireless Magnetic Switch Mechanical Keyboard represents the next evolution in input technology-blending intelligent design, superior materials, and magnetic precision to deliver uncompromising performance. Featuring Gateron's Double-Rail Magnetic Hall Effect Switches, this compact full-size (96%) keyboard enables per-key actuation point customisation in 0.1 mm increments, redefining how keystrokes are registered and released.

With features like Dynamic Rapid Trigger, programmable analogue input, and up to four distinct keystroke actions per key (via Dynamic Keystrokes), the K4 HE is engineered for those who demand responsiveness, flexibility, and personalisation. Whether you're engaged in competitive esports, creative content development, or high-efficiency workflows, the K4 HE adapts to your unique input style with remarkable accuracy.

Equipped with a high-speed MCU and supporting both wired and wireless operation-including 2.4GHz ultra-low-latency mode and Bluetooth 5.1-the K4 HE offers up to a 1000 Hz polling rate across all connection types, ensuring lightning-fast performance and cross-platform compatibility. The QMK-compatible firmware and browser-based Keychron Launcher app allow intuitive control over remapping, macros, and actuation depth-no software installation required.

Elegantly housed in a robust aluminium frame with premium rosewood accents and outfitted with double-shot PBT OSA profile keycaps, this keyboard is acoustically tuned for a refined "thock" and tactile typing experience. Advanced sound-dampening layers reduce resonance while enhancing acoustic clarity, delivering satisfying feedback with every press.

This is not just a keyboard-it's a fully customisable input engine, built for those who demand precision and versatility without compromise.
