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 K3 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). 

Check out the video above demonstrating how to remap the Light Effect key (located on the K3 Pro’s top right corner) to an Eject key with the VIA software, so you can get a shortcut to put your Mac to sleep (Command-Option-Eject), or even remap the fn key in a breeze. It’s never been so intuitive and flexible to personalize your own keymap.

An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Suitable For All Devices

Offers a Mac layout while still being compatible with Windows, the K3 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 (and additional esc and enter keys) to allow you to switch between operating systems with ease.

An Epic Core Inside

A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz on wired mode right out of the box, which makes the latency hardly noticeable even in competitive games.

Hot-swappable

We all have our unique typing preferences, that’s why we are offering hot-swappable option on the K3 Pro, so you can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering.

*The K3 Pro is currently compatible with Gateron low-profile mechanical switches only, as QMK does NOT support low-profile optical switches.

Low-Profile Gateron Switch

The Gateron low-profile MX 2.0 Mechanical switch is designed to enhance reliability. Gateron's reputable switches are your best choice for a precise, smooth, and reliable fingertip feel whether you prefer linear (red), clicky (blue), or something in between (brown).

The best keyboard ever I've used

This is one of the keyboards I will never forget. The tactile feel is amazing and so is the construction. I believe that if Keychron improves its products even more, I will continue to buy them.

In terms of improvements, it is really only necessary on the keys that come from the factory in the alignment of the letters on the keys (caps lock, backspace, enter and tab) but nothing that is ugly or that diminishes the beauty of this keyboard

Feels so speedy and pleasant to type on!

I love the 75% layout and Keychon nails it here. The material of the keys feels really nice to type and the shape plus the size of the keys makes you feel like you're just zipping along typing on the keyboard. The pop-back from the keys is so responsive. I have the original K3 from the Kickstarter and I didn't expect the Pro to feel so different, but it's fantastic. I'd recommend getting the shine through keys add-on if you want the backlight to really stand out!

I admit was a little at a loss for how to handle the media keys because I had never used VIA before to remap and the documentation is a bit barebones. By default, media keys just do the normal F1/2/etc functions and you have to press the FN key to get the media functions, while I prefer the other way around. However, you can use VIA to swap it around by putting the media functions on the third layer instead (the default Windows layer, shows up as Layer 2 in VIA since the first layer is 0) and then putting the FN functions on the fourth layer (the layer pressing Fn switches to). Also, VIA doesn't have a FN key listed, that was confusing at first. Keychron just uses the FN key as a Layer activator, so if you want to remap it (I also swaped FN with Right Alt), you need to pick one of the MO(0/1/2/3) buttons from the Layers section as the replacement depending on what layer you want it to launch. MO(3) corresponds to activating the fourth layer.

It's definitely a more manual process than just using the old FN lock shortcut on the original K3, but if the change was necessary for proper VIA support, it was worth it — and so is this keyboard!

Great Mechanical Keyboard!

I wanted to try this keyboard for a few weeks before leaving this review and overall I Love the form factor and feel of the k3 Pro. When I Initially opened it I was amazed at how this keyboard did not need mods out of the box despite being built and created for that purpose in mind which surprised me but if you do decide to mod it, will greatly improve the feel by a mile like I will in the future. 10/10 highly satisfied.

Difference like 60 & 144 Hz

The last two years I was using the K3 V2 as my go-to and travel keyboard. It has the perfect size and the low profile keycaps save a lot of space in the backpack.

When I saw there will be a K3 Pro I knew I had to get it and I'm definitely not disappointed. The K3 Pro feels a little heavier and more stable than the old V2. The PBT-Keycaps give it a nice feel and consistent, clean look. The keyboard is fixing issues I didn't knew my old V2 had before I used the K3 Pro. The stabalizors are way better than before and the feet give a way better impression of quality and sustainability.

The possibility of designing your own macros or mapping keys with QMK/VIA is easy to initalize and use. Just connect your keyboard and then follow the instructions on the via-website.

Definitely would buy this keyboard or it's successor again

Excellent ultra-slim mechanical keyboard

In the past I have used an MX Mechanical Mini with brown switches which has been an excellent keyboard. After wanting some blue switches and something a little more customizable I got this keyboard. It has been excellent so far. The build quality is great and the switches and keycaps feel better than on the MX Mechanical. I do wish that the keyboard reported its battery level in the Bluetooth settings on MacOS like the MX Mechanical though. Customization through VIA has been great and super useful for software development.
