Tastiera meccanica wireless Keychron K2 Special Edition bianco retroilluminazione RGB, layout compatto 75%

The Keychron K2 HE is a compact 75% wireless mechanical keyboard in a white Special Edition finish with RGB backlighting. It uses Gateron Nebula magnetic switches with Hall sensor technology and offers hot-swappable functionality, multiple connectivity modes (USB-C wired, 2.4 GHz dongle and Bluetooth 5.2), and a 4000 mAh battery for extended use. The model includes natural rosewood accents, double-shot PBT OSA keycaps, an aluminum mounting plate and built-in sound-absorbing materials to provide a comfortable, low-noise typing experience.

Advantages

The K2 HE features pre-lubricated magnetic Gateron Nebula switches with 0.1 mm sensitivity and adjustable trigger points from 0.2 mm to 3.8 mm, enabling precise customization of key actuation. Dynamic features such as Last Keystroke Prioritization, Snap Click and Dynamic Rapid Trigger optimize responsiveness for gaming, while Dynamic Keystrokes and Analog Mode allow up to four actions per key based on press depth for advanced control schemes. Open QMK support and the Keychron Launcher app provide extensive remapping, macro and lighting customization. The keyboard supports NKRO in wired and wireless modes and offers a 1000 Hz report rate in wired and 2.4 GHz modes for minimal input latency.

Suitable for

• Typing and office work where compact layout and low noise are desired
• Competitive and casual gaming requiring fast response and customizable triggers
• Content creation and programming with programmable keys and macros
• Multi-device workflows using Bluetooth 5.2 or the 2.4 GHz receiver

How to use

Connect the keyboard via USB-C for wired mode or plug the included 2.4 GHz receiver into your computer for high-performance wireless operation; alternatively pair up to three devices via Bluetooth 5.2 and switch between them using the system switch. Install Keychron Launcher to remap keys, create macros, set trigger points and customize RGB lighting. Use the hot-swap sockets to change switches without soldering, and adjust tilt angle using the built-in feet for ergonomic positioning.

Recommendations

For gaming, use the 2.4 GHz mode at 1000 Hz or wired connection to minimize latency. When customizing trigger points or Dynamic Keystrokes, test settings gradually — change one parameter at a time to find the preferred actuation depth and response. To maximize battery life, reduce backlight brightness or turn off RGB effects when they are not needed.
