Product Description

The Keychron S1 is a compact 75% mechanical keyboard with a low profile design, suited for users who want a slim, customizable typing tool with solid build quality. It fits well for hobbyists who enjoy modifying keyboards, Mac users needing dual layout support, and gamers seeking low latency. Its all-metal body and hot-swappable low profile switches offer flexibility but limit switch options to Gateron low profile types.

Key Features

Low profile Gateron MX 2.0 mechanical switches provide a precise and smooth typing feel with options for linear, tactile, or clicky feedback.
Hot-swappable sockets allow switch changes without soldering, simplifying customization within the supported switch range.
Full QMK and VIA firmware support enables extensive key remapping and macro programming for personalized layouts and shortcuts.
Dual system layout toggle with extra keycaps supports both macOS and Windows, allowing seamless switching between operating systems.
Adjustable tilt angles (3° and 6°) help optimize wrist comfort during extended use.
RGB backlighting offers 22 effects with customizable brightness and speed, enhancing visual feedback.

Build Quality

The keyboard features a CNC-machined aluminum body that is slim yet sturdy. The steel plate and plate-mounted stabilizers contribute to stable keypresses. Low profile double-shot PBT keycaps resist oil and wear, maintaining legend visibility over time. The design supports compatibility with low profile, XDA, and DSA keycaps for further personalization.

Typing Experience

The low profile switches reduce key travel, which can speed up typing and reduce finger fatigue. The double-shot PBT keycaps improve texture and durability. The north-facing RGB LEDs minimize light bleed and maintain a clean look. The keyboard’s slim profile and adjustable feet help users find a comfortable typing angle.

Compatibility and Connectivity

The S1 connects via a wired Type-C cable and includes a Type-A to Type-C adapter. It is designed primarily for desktop use without wireless options. The keyboard supports macOS and Windows layouts with a system toggle and dedicated keycaps for each. Firmware customization is available through open-source QMK and VIA software.

Trade-offs

Switch options are limited to Gateron low profile mechanical switches, restricting variety for users preferring other brands or switch types.
Only wired connectivity is available, which may be less convenient for users seeking wireless setups.
The low profile design may not suit users who prefer traditional key travel or a higher typing angle.
