Mechanical keyboard Keychron K1M-H3 — 80% 87-key, USB + RF Wireless + Bluetooth, RGB backlight, black

Keychron K1 Max is an ultra-slim wireless low-profile mechanical keyboard with an 80% TKL layout that supports 2.4 GHz, Bluetooth 5.1, and wired USB connections. Powered by an ARM MCU with 256 KB flash and QMK firmware compatibility, it provides customizable key remaps and macros via the Keychron Launcher web app. The keyboard includes LSA low-profile keycaps for both macOS and Windows, low-profile double-shot PBT keycaps, redesigned stabilizers, interior IXPE acoustic foam and latex support foam for quieter, more responsive typing, and optional hot-swappable support for Gateron low-profile MX mechanical switches on the RGB Backlight Hot-Swappable version.

Advantages

The K1 Max combines a thin aluminum chassis and low-profile Gateron switches to deliver a compact, slim mechanical typing experience with a 1000 Hz polling rate on 2.4 GHz and wired modes. It offers multi-device Bluetooth pairing for three devices, full macOS and Windows compatibility with included modifier keycaps, and extensive customization through QMK and the Keychron Launcher web app. Optional hot-swap capability allows easy switch replacement without soldering (compatible with Gateron/Keychron low-profile mechanical switches only).

Key specifications

How to use

Connect the keyboard via USB, pair over Bluetooth 5.1 with up to three devices, or use the 2.4 GHz dongle for a low-latency 1000 Hz experience. Install or open the Keychron Launcher web app on macOS, Windows, or Linux to program keymaps, macros, and shortcuts using QMK features. If you have the hot-swappable RGB version, gently pull out a low-profile Gateron switch and insert a replacement without soldering; follow standard anti-static precautions when changing switches.

Recommendations

For gaming with minimal latency, use the 2.4 GHz connection or wired mode. For multi-device workflows, pair via Bluetooth. If you plan to change switch feel, choose the hot-swappable RGB version and use only compatible Gateron/Keychron low-profile mechanical switches.
