Keychron K4 Pro Red Switch RGB (ISO-CH)

Keychron K4 Pro - The Best of Both Worlds

The K4 Pro is the world's first wireless programmable QMK/VIA keyboard, paving the way for a new era of mechanical keyboards. It handles all keys and macro commands via VIA, includes keycaps for Windows and macOS, and can be easily swapped out with any mechanical MX switch. Together with our signature features and improved typing noise, the K4 Pro takes the typing experience to a whole new level with endless possibilities.

Wireless and wired

An excellent solution for multitasking. You can wirelessly connect the K4 Pro to up to 3 devices via its stable Broadcom Bluetooth 5.1 for seamless multitasking with your laptop, phone and tablet. Quickly switch between devices. It is fully compatible with both Mac and Windows. A reliable wired USB Type-C port is also available if you need it.

Program the K4 Pro with QMK & VIA

QMK/VIA literally means endless possibilities for a fluid workflow. Thanks to the Keychron engineering team, this is the first time in history that a wireless, mechanical keyboard has offered this type of functionality. Simply connect the K4 Pro to your device with a cable and drag and drop your favorite keys or macro commands to remap any key on any system (macOS, Windows, or Linux). It has never been so intuitive and flexible to personalize your own keyboard layout. A brand new, low-power Arm Cortex-M4 32-bit STM32L432 MCU, which is powerful and equipped with 128K flash, offers more flexibility for developers.

Improved typing experience

The K4 Pro has been completely redesigned and redesigned to improve the typing experience. The added sound-absorbing foam, thick silicone cushioning at the bottom, and steel plate provide responsive feedback and a quiet typing sound, while the added weight increases stability when the K4 Pro is on the desk.

Suitable for all devices

The K4 Pro offers a Mac layout while still being compatible with Windows. It's one of the few keyboards on the market that has the same multimedia and function key features as Apple's keyboards for Mac users, but with better tactile feedback. You can even configure different key bindings for Mac and Windows devices. The VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for macOS and Windows (4 each) so you can easily switch between operating systems.

Hot-swappable

Every detail is important for a personalized typing experience, so we give you the opportunity to do so. You can hot-swap out any switch on the K4 Pro for almost any MX-style 3-pin and 5-pin mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without the need for soldering. You can customize your own typing experience in a matter of seconds.

Screw-in PCB stabilizers

Even small parts are important for your sensitivity. We've included bolted stabilizers on the PCB that allow for smoother typing with less wiggle on the large keys like Spacebar, Shift, Enter, and Delete. You can even customize them with alternative stabilizers like Cherry or Durock.

Factory pre-lubricated Keychron K Pro switches

The K4 Pro is equipped with the unique OSA profile (OEM spherical angle profile) and translucent ABS keycaps, which provide a more comfortable feel for the fingertips and excellent oil resistance for long-term use.

South-facing RGB lighting

The south-facing RGB lighting is designed to better illuminate the keyboard's backlight from the user's point of view. The south-facing RGB lighting also doesn't interfere when the user installs alternative keycaps with a cherry profile on their keyboard. The keyboard has 22 different RGB backlight settings, as well as a static white backlight option. You can easily fine-tune the RGB hue, saturation, brightness, and effect speed.

Ergonomic support

Three levels of adjustable typing angle (3, 7 and 10 degrees), an inclined lower frame and curved OSA profile keycaps provide long-lasting ergonomic support for your wrist.
