## Summary description

The Keychron K3 Max is a 75% mechanical keyboard featuring 84 keys, RGB LED backlighting, and versatile connectivity options including USB, RF Wireless, and Bluetooth. Ideal for universal use, it combines functionality with a sleek grey design.

## Long description

The Keychron K3 Max is a low-profile 75% mechanical keyboard with 84 keys that supports USB, 2.4 GHz RF wireless, and Bluetooth 5.1 connections. It features QMK firmware compatibility, low-profile Gateron mechanical switches, double-shot PBT keycaps, interior acoustic foam, and adjustable typing angles, offering a compact grey keyboard suited for both Mac and Windows users.
Advantages
The K3 Max provides multiple connection modes including a 1000 Hz polling-rate 2.4 GHz wireless mode and Bluetooth 5.1 for pairing with up to three devices. Its ultra-slim aluminum design uses low-profile Gateron switches for reduced height while preserving tactile response. Built on an ARM MCU with 256 KB flash and QMK support, the keyboard allows extensive remapping, macros, and customization via the Keychron Launcher web app. Additional features include hot-swappable switch options (for low-profile Gateron switches), redesigned stabilizers, IXPE acoustic and latex foam for quieter, more responsive typing, and RGB or white backlight options.
Suitable for
Compact desktop setups where desk space is limited
Users who switch frequently between Mac and Windows systems
Gamers seeking low latency in 2.4 GHz or wired modes
Developers and power users who customize keymaps with QMK
Typists who prefer low-profile mechanical switches and quiet keystrokes

How to use
Connect the K3 Max to a device via USB, 2.4 GHz dongle, or pair it using Bluetooth 5.1 to one of three devices. Install and open the Keychron Launcher web app on macOS, Windows, or Linux to remap keys, create macros, and switch between Mac and Windows keymaps. If you have the hot-swappable version, power off the keyboard before removing or installing low-profile Gateron switches; press gently and replace switches without soldering. Use the included macOS and Windows keycaps to match your operating system layout as needed.
Usage recommendations
For the lowest latency during competitive gaming, use the 2.4 GHz or wired connection. Use the Keychron Launcher to save separate keymaps for macOS and Windows. Replace switches only with compatible Keychron or Gateron low-profile mechanical switches and follow anti-static precautions when opening the keyboard.
