The Keychron K3 Max is a slim, wireless mechanical keyboard with 2.4 GHz radio, Bluetooth and wired connection. It enables all keys and macro commands on the 75% layout to be controlled via VIA. LSA (Low Profile Spherical Angled) keycaps are available for Windows and macOS, and the Gateron low-profile MX switches are easy to replace. Thanks to the three connection options and the compact layout, the K3 Max can be taken almost anywhere - ideal for mobile use. The low-profile 2.0 switches from Gateron offer high reliability and ensure a precise, smooth typing feel. The K3 Max offers a Mac layout, but is also customisable for Windows. It supports VIA on macOS, Windows and Linux. Keycaps for both systems are included for easy switching. An ARM-based chip with 256 KB flash provides flexibility. The polling rate of 1000 Hz in 2.4 GHz and cable mode minimises latency, even in games. The hot-swap function allows Gateron low-profile switches to be changed quickly and without soldering to customise the typing experience. The K3 Max uses durable double-shot PBT keycaps that are resistant to wear and oil and provide a high-quality typing feel. The K3 Max is only compatible with Gateron mechanical low-profile switches, as QMK & VIA do not support optical low-profile switches.
