Full Metal And Ultra-Slim Body

It’s incredible to make such a slim keyboard with a solid piece of aluminum. The whole body of the keyboard is processed through CNC machined, polished, anodized, sandblasted, and undergoes 24 more manufacturing stages to make the S1 slim, elegant and solid. 

A Customizable Low Profile Keyboard

To build a customizable low profile keyboard, we designed every part that is easy to assemble. Therefore, you can customize and adjust each component if you want.

An Epic Core Inside The Keyboard

A powerful MCU ARM structure that is armed with 128K Flash provides more flexibility for developers. The polling rate is 1000 Hz out of the box, which makes latency non-existent for the competitive game.

Low Profile Double-Shot PBT Keycaps

We created a new low profile double-shot PBT keycaps set for the S1. The PBT keycaps will provide excellent oil resistance, enhance the type feel, and prevent the legends from fading.

Switch Layouts Between macOS & Windows

Built with the Mac users’ experience in mind while still retaining compatibility for Windows devices, the Keychron S1 comes with a system toggle and an additional set of customized keycaps for both Windows and macOS systems. You can now save two different layouts on the keyboard, one for each system.

Adjustable In Two Angles

The S1 has two extra feet that allow you to adjust the tilt angle of the keyboard. One is 3°, and another is 6°, enabling you to find the most comfortable angle for your wrist.

Program S1 With QMK & VIA

With full QMK and VIA support, you can easily program and remap each key on the keyboard. The open-source firmware means endless possibilities for keyboard layouts, shortcuts, backlight effects, and more. 

Get The S1 Keymap Working On VIA

Since the VIA code for the S1 is still awaiting approval from Github, it is not yet automatically recognized, you will need to manually download and import the S1 keymap.

 To get started, please follow the steps: 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 S1 keymap working on VIA.
