## Long description

Keychron KJ5-H4 is a full-size (100%) mechanical keyboard in a standard QWERTY English layout with 108 keys and a black straight form-factor design. It supports wired USB connectivity and multiple wireless modes, and features customizable RGB LED backlighting. The keyboard is built with acoustic foams and Keychron Super switches for a consistent tactile response and enhanced typing sound. Configurable with QMK firmware and the Keychron Launcher web app, it provides flexible key remapping, macro programming and lighting customization to suit both work and gaming environments.
Advantages
The keyboard combines a full-size layout with a 1000 Hz polling rate (in wired and 2.4 GHz wireless modes) and a responsive wireless connection via 2.4 GHz or Bluetooth. Multiple layers of acoustic foam improve keystroke sound and feel while double-shot PBT keycaps ensure durability and resistance to wear. The hot-swappable option allows easy switch replacement without soldering, and the preinstalled Keychron Super switches are rated for long life and higher light transmittance for brighter RGB effects. Open-source QMK support and the Keychron Launcher web app permit extensive customization of keys, macros and lighting profiles.
Suitable for
 Gaming with fast-response 2.4 GHz wireless or wired USB connection
 Typing and productivity tasks requiring a full-size numeric keypad
 Users who want customizable key mapping and macros via QMK
 Environments where quieter, refined typing acoustics are preferred

How to use
Connect the keyboard via the included USB cable for immediate wired operation or insert the 2.4 GHz receiver into a Type-A port for low-latency wireless use. To pair via Bluetooth, switch to Bluetooth mode and follow device pairing procedures to connect up to three devices. Use QMK firmware or the Keychron Launcher web app to remap keys, record macros, and configure RGB lighting profiles. If your unit is the hot-swappable version, remove and replace switches by pulling out the existing switch and inserting a compatible 3-pin or 5-pin MX-style switch without soldering.
Usage recommendations
For gaming, use the 2.4 GHz receiver or wired USB connection to benefit from the 1000 Hz polling rate and enable Last Key Priority if supported by firmware for faster directional input. For quieter typing, install the provided acoustic foams and choose switches with softer actuation; maintain double-shot PBT keycaps by cleaning with a soft, damp cloth and avoid harsh chemicals. Regularly update firmware via QMK or Keychron tools to access performance and compatibility improvements.
