Keychron S1 is the first 75% layout all-metal low profile custom mechanical keyboard. With its all-metal ultra-slim CNC machined body, QMK/VIA support, and low profile double-shot PBT keycaps, the S1 gives you a high-end typing experience, a unique design setup, and endless possibilities. One of a kind.
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 ultra-low-power ARM architecture MCU equipped with 128K Flash will provide more flexibility for developers. The polling rate is 1000 Hz right out of the box, which makes the latency hardly noticeable even in competitive games.
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.
The hot-swappable sockets are mounted on the PCB, so you can install or change the switches without soldering. The PCB only supports Gateron low profile mechanical switches.
22 RGB Light Effects
Comes with up to 22 types of RGB backlight effects, you can choose the one fit your mood. And you can further fine-tune the RGB hue, saturation, brightness, effect speed with ease.
Gateron Low Profile 2.0 Mechanical Switch
The optimized molded Gateron low profile MX 2.0 Mechanical switch is designed to enhance reliability. Gateron's reputable switches are your best choice for a precise, smooth, and reliable fingertip feel, whether you prefer linear (red), clicky (blue), or something in between (brown).
