Keychron L1 Mechanical Keyboard

The Keychron L1 is a 75% wireless mechanical keyboard designed for gamers and users who want flexible connectivity with low latency. It supports 2.4 GHz wireless, Bluetooth, and wired modes, allowing seamless switching between up to three Bluetooth devices. Its hot-swappable switches and customizable keymapping suit hobbyists and professionals who value personalization and fast response times.

Key Features

• Supports 2.4 GHz wireless with a 1000 Hz polling rate for responsive input, plus Bluetooth 5.1 and wired USB-C connection.
• Hot-swappable switch sockets compatible with most 3-pin and 5-pin MX-style switches, enabling easy switch replacement without soldering.
• Customizable keymapping via open-source QMK/VIA software and Lemokey Launcher, allowing macros and remaps across macOS, Windows, and Linux.
• South-facing RGB lighting with 22 preset modes and adjustable effects, optimized for non-shine-through PBT keycaps.

Build Quality

• Full CNC-machined aluminum frame provides rigidity and durability.
• Polycarbonate plate combined with double-gasket mount and dual layers of sound-dampening foam improves typing acoustics and comfort.
• Equipped with screw-in PCB stabilizers to reduce key wobble on larger keys.
• Durable double-shot Cherry PBT keycaps resist wear and oil buildup over time.

Typing Experience

• Pre-lubed Gateron Jupiter switches (on fully assembled models) offer smooth keystrokes and quieter operation.
• Flexible mounting and foam layers soften typing sound and provide tactile feedback without harsh noise.
• Hot-swappable design allows users to tailor switch feel and sound to their preference.

Connectivity

• 2.4 GHz wireless mode offers low latency comparable to wired connection, suitable for gaming.
• Bluetooth mode supports up to three devices with easy toggling, useful for multitasking across devices.
• Wired USB-C connection provides stable input with latency under 1.5 ms, ideal for competitive gaming or programming.

Compatibility and Layout

• Available in ANSI (US) and various ISO layouts, including UK, German, Nordic, and Swiss, with barebone options for custom builds.
• Fully compatible with macOS, Windows, and Linux operating systems.
• Open-source firmware allows extensive customization and community support.

Trade-offs

• Bluetooth polling rate is lower (90 Hz) than wired and 2.4 GHz modes, which may affect responsiveness in wireless multitasking.
• Keycaps are non-backlight shine-through, limiting RGB visibility through legends.
• Heavier weight and full aluminum frame reduce portability compared to plastic or smaller keyboards.
• Unknown battery life duration under typical use.
