UK Keychron K4 Pro Bluetooth QMK/VIA RGB Assembled Tactile Mac/PC Custom Keyboard - K4P-H3-UK

Wireless and Wired
An excellent solution for multitasking. You can connect the K4 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly, and its fully compatible with both Mac and Windows.
A reliable USB Type-C wired connection is also available when you need it.

Program with QMK & VIA
QMK/VIA means endless possibilities for a fluid workflow. Thanks to our engineering team, it's the first time in history that a wireless mechanical keyboard has these kinds of capabilities right out of the box.
Simply connect the K4 Pro to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux).
A powerful ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU equipped with 128K Flash will provide more flexibility for developers.

Upgraded Typing Experience
The K4 Pro has been re-engineered and redesigned from the inside out to upgrade the typing experience. The added sound-absorbing foam, a thick silicone dampening bottom pad, and steel plate provide responsive feedback and a peaceful typing sound, while added weight will enhance the stability.

Suitable For All Devices
Offers a Mac layout while still being compatible with Windows, the K4 Pro is one of the few on the market that has the same multimedia and function key functions as Apple keyboards for Mac users, but with more tactile feedback.
You can even configure different keymaps for both Mac and Windows devices. While VIA software is compatible with macOS, Windows, and Linux. Includes keycaps for both macOS and Windows (3 keycaps for each) to allow you to switch between operating systems with ease.

Every detail matters, so we make the K4 Pro hot-swappable for your personalized typing experience. The hot-swappable sockets are mounted on the PCB, so you can hot-swap every switch on the K4 Pro with almost all of the 3pin and 5pin MX style mechanical switches on the market (including Cherry, Gateron, Kailh, Panda, etc.) without soldering. You can customize your own typing experience in seconds.

Screw-In PCB Stabilizers
Even small part matters for your fingertip feel. Weve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as space bar, shift, enter, and backspace. The Keychron K4 Pro also supports third-party screw-in PCB stabilizers.

OSA Profile ABS Backlight Shine-Through Keycaps
To further leverage your typing experience, the K4 Pro ISO version comes with our unique OSA profile (OEM profile with spherical angle) and ABS keycaps that aim to provide a more comfortable fingertip feel and a fantastic backlight shine-through effect.

Pre-lubed Keychron K Pro Switch
By optimizing the switch mold, the K Pro switch wobbles less than a standard mechanical switch and feels smoother on each hit. Plus, the factory pre-lubed process on all the K Pro switches (exclude the clicky ones), no doubt this will ensure the best smoothness at your fingertips when typing.

Ergonomic Support
Three levels of adjustable typing angle (3, 7 & 10) and curved OSA-profile keycaps are all working together to provide long-lasting ergonomic support for your wrist.

The product is absolutely fabulous, earlier I was thinking to buy directly with keychron but later decided to go with keyboard company. Considering my first time order with them and I was bit afraid but after speaking with customer service it was so smooth and I would recommend buying with them as they offer best service.

Brought the Keychron K4 Pro, it's my first mechanical keyboard and so far it feels great! Getting use to the new layout, I needed the numpad for work but also didn't want to get a fulll size so this was a good alternative.
Keyboard arrived in good time and was very well packaged. Will deffo shop here again!
