Ultra-Slim The innovative low-profile Gateron switch is 31% slimmer than conventional normal profile switches makes the aluminum body K5 Max one of the thinnest wireless mechanical keyboards in the world. While still delivering a distinguished tactile response. 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 K5 Max 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). Get the K5 Max keymap working on VIA Since the VIA code for the K5 Max version 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 K5 Max keymap working on VIA. Suitable For All Devices Offers a Mac layout while remaining compatible with Windows. It stands out in the market by providing the same multimedia and function key functions as Apple keyboards for Mac users, but with enhanced tactile feedback. An Epic Core Inside A powerful ARM architecture MCU equipped with 256KB Flash will provide more flexibility for developers. The polling rate is 1000 Hz on 2.4GHz and wired modes right out of the box, which makes the latency hardly noticeable even in competitive games. Interior Acoustic Foam Elevate your typing with K5 Max featuring advanced IXPE acoustic foam for silent keystrokes and enhanced comfort, coupled with resilient latex foam for superior key switch support, responsiveness, and durability. Redefining the standard for a quiet, comfortable, and responsive typing experience. Hot-Swappable (Optional) We also provide a hot-swappable version for your choice, which means you can customize your typing experience without soldering, pop them in and it's done. We all have our unique typing preferences, that’s why we are offering hot-swappable option on the K5 Max, so you can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering. *The K5 Max is currently compatible with Gateron / Keychron 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) or bumpy (brown).
