2.4 GHz & Bluetooth Connection  

Discover enhanced performance with the Q3 Max Keyboard, featuring a 2.4 GHz wireless connection and a rapid 1000 Hz polling rate for responsive use. It also offers Bluetooth 5.1 connectivity, allowing easy and efficient multitasking by connecting with up to three devices, such as your computer, phone, and tablet, with quick switching capability.


A Refined Piece of Metal Art

The entire metal body is crafted with 6063 aluminum that is processed through CNC machined, polished, sandblasted, and undergoes 24 more manufacturing stages to make this solid metal piece of art that is the Q3 Max. 


Significantly Enhanced Acoustic Foams

Elevate the typing experience with a combination of premium acoustic foams such as IXPE, PET, and Latex. Each keystroke becomes enjoyable, making every tap a delight for the senses.

Easy Assemble

We designed every component to be able to assemble easily so you can customize and adjust each component with ease to create your ultimate typing experience.


An Epic Core Inside The Keyboard

A powerful ARM Cortex-M4 chip (MCU) equipped with 256K Flash will provide more flexibility for developers. The polling rate is 1000 Hz right out of the box on 2.4 GHz and wired modes (90 Hz on Bluetooth mode), which makes the latency hardly noticeable even in competitive games.

Double Gasket Design

The Double Gasket Design is a new innovative structure in the industry. In addition to the gaskets on the plates, we added silicone pads between the top and bottom cases to significantly reduce the acoustic resonance between the metals and reduce the noise of the impacted metals. This design allows the keyboard to maintain the flexibility of the gasket structure and improves the overall typing sound. 

Double Gasket Design of Keychron Q3 Max Mechanical Keyboard

Experience the next level of key sounds and comfort with our gasket mount design together with a flexible PC (Polycarbonate) plate. This design combination allows the keyboard to maintain the flexibility of the gasket structure and improves the overall typing sound.

OSA Double-Shot PBT Keycaps

To further fine-tune your typing experience, the Q3 Max ISO comes with our unique OSA profile (OEM profile with spherical-angle) and double-shot PBT keycaps that aim to provide a more comfortable fingertip feel with excellent oil resistance for long-term use on the TKL layout.

Switch layouts between macOS & Windows

Built with the Mac users’ experience in mind while still retaining compatibility with Windows devices, the Keychron Q3 Max 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.

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.

You can easily customize the Q3 Max's knob to your desired key or macro commands such as: zooming in/out, adjusting screen brightness, brush size, volume, selecting video clips or photos, or backlight hue.

Program Q3 Max 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. 

Check out the video above demonstrating how to remap the RGB Mode + key to an Eject key with the VIA software to create a shortcut to put your Mac to sleep (Command-Option-Eject).

Get the Q3 Max keymap working on VIA

Since the VIA code for the Q3 Max is still awaiting approval from Github, it is not yet automatically recognized. Please download the appropriate keymap JSON file below, open VIA, turn on "Show Design tab" on "Settings" tab, and drag the JSON file into the “Design” tab on VIA to get the Q3 Max keymap working on VIA.

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 with the premium non-shine-through PBT keycaps installed. The south-facing RGB is also free from interference when the users install OEM or Cherry-profile alternative keycaps on the keyboard.

Gateron Jupiter Switch

Our exclusive Gateron Jupiter mechanical switch (for the Fully Assembled version only) comes with a 3-pin design, its pre-lubed with a reliable Gateron quality standard with up to 80 million keystrokes lifespan. While their unique LED diffuser design offers high RGB backlight transmittance and softer backlight effect.

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 Q3 Max also supports third-party screw-in PCB stabilizers.

Customer Reviews

Based on 1 review
Love it. Might have problems with VIA though.

Love it, like any other keyboard here. Very solid out of the box. Didn't have to do any mods to make it sound right. For preference I did swap out switches and keycaps, but, it already sounded great out of the box.
The only thing I didn't like and haven't found a solution for is the connection to VIA. However, more people are having this problem it seems. I hope this gets resolved soon.
