All-Around Customizable Keyboard

To build a fully customizable keyboard, we designed every component to be easily assembled so you can customize and adjust any or every parts the way you want.

Note: The screw heads are molded into the case, so they have a very strong grip and won’t fall out.

An Epic Core Inside The Keyboard

A powerful ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz out of the box, which makes latency non-existent for the competitive game.

Switch Layouts Between macOS & Windows

Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Keychron V3 comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.

Program V3 with QMK & VIA

With full QMK and VIA support, you can easily program and remap each key on the keyboard. The open-source firmware means endless possibilities for keyboard layouts, shortcuts, backlight effects, even the knob, and more.

Programmable Knob

Designed to enhance your creative workflow, its aluminum rotary encoder allows you to customize your favorite keys and macros on the knob through the VIA software with ease.

You can easily customize the V3's knob to your desired key or macro commands like zooming in/out, adjusting screen brightness, brush size, volume, selecting video clips or photos, or backlight hue.

The hot-swappable sockets are mounted on the PCB, so you can install or change the switches without soldering. The PCB supports both 3-pin and 5-pin MX mechanical switches.

South-facing RGB LED Lights.

The south-facing RGB LED is designed to better illuminate the keyboard backlight from the typist’s angle. The south-facing RGB is also free from interference when the users install OEM or Cherry-profile alternative keycaps on the keyboard.

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.

Keychron K Pro Switch Features
All New Screw-In PCB Stabilizers

All New Screw-In PCB Stabilizers

The screw-in design increases stability and makes it easier for changes and upgrades. Precise craftsmanship makes the stabilizers more stable and less shaky. The big keys’ (space bar, shift, enter, delete) typing experience is now more stable and smooth. The Keychron V3 also supports third-party screw-in PCB stabilizers.

Great first mechanical keyboard

I like the smooth feel of the linear switches and the keys feel great
It's also nice to have everything closer together with the TKL board and the numpad being separate.
Night and day difference to the membrane board and feels lovely to type on
Feels so solid and heavy, I have to learn to type again without hitting the other keys since they are easily hit.
It's also nice to have the keyboard central rather than off to one side, way better ergonomics.
No double pressing of the keys so far and does feel faster to type on.
Pleased with the purchase so far.

Ben Bass
Good enough that I bought a second one

Very pleased with this keyboard, very nice to type on, great build quality, and the knob is more useful than I expected. Not perfect though, eg a context-menu key for Windows would have been nice, and not managed to get Via remapping to work yet.

Best keyboard I've ever used!

Fantastic keyboard. OSA profile is really nice too, shame custom keycaps are hard to find in OSA.

Matthew Bray
Best keyboard I've used in a very long time

Overall very happy with the keyboard, bar space bar does make a rather unsatisfactory sound that is louder than all the other keys, therefore dropping one star - would only be half a star if that were submissable!

Fantastic keyboard for a great price

Love this keyboard. Build quality is excellent. The lights look great. Lots of customisation options both mechanical and software based. Very happy would highly recommend.
