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.

OSA Profile ABS Backlight Shine-Through Keycaps

To further leverage your typing experience, the V3 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.

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, and more.

Programmable Knob

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

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.

All New Screw In PCB Stabilizers Keychron V4 Custom Mechanical Keyboard

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, backspace) typing experience is now more stable and smooth. The Keychron V3 also supports third-party screw-in PCB stabilizers.

damn confortable !

for a mechanical keyboard, the confort and the (near-)silence when typing is unbelievable !! It's really great !

Clavier de qualité

Clavier confortable pour l'écriture au quotidien.
Matériaux de qualité et son très appréciable.
Facile à configurer avec VIA.

Un seul point négatif pour ma part, j'ai un switch brown qui a un défaut de fabrication, il ne s'enfonce pas correctement dans la backplate. Le switch est légèrement penché à cause d'une épaisseur.
Malgré tout il fonctionne.

Best keyboard for coding on osX!

Love the layout, great feel with the brown keys, solid chassis, sturdy connection. What more could anyone want?

First mechanical keyboard!

For a first mechanical keyboard, I must say that the change from an ordinary keyboard is total. This on is bulky and feels indestructible! The typing is firm and pleasant. The sound of the space bar is also very nice. The only drawback, as I took an AZERTY version, is the lack of some special characters on some of the keys. I didn't find any set of special keys for my use on the keychron site, so I'll search for another solution. Overall, it's a nice tool!
