Si75-HE - Blue
NEW
High Performance Hall Effect Keyboard
Introducing the Si75-HE — a high-performance Hall-effect keyboard from ONEofZERO, powered by Keychron. This keyboard balanced gaming performance, refined typing feel, and modular customization.
At its core is Silicore, ONEofZERO’s signature design framework that enhances acoustics and comfort while serving as a modular ecosystem for aesthetic customization — a true form meets function implementation.
Modular Silicone Ecosystem
The Si75-HE’s modular silicone ecosystem enhances acoustics and feel while introducing a new layer of visual expression through customizable, interchangeable components.
**After-market Modular Silicone Expansion Kits available for resale. Available in Red, Blue and Orange.
Gasket Mount Design
Silicone strips isolate the Plate and PCB from both the top and bottom case to provide vibration-dampened typing experience with a softer, more defined sound and feel.
Frosted Case
Frosted transparent ABS case reveals subtle pops of color from internal silicone components for a customizable aesthetic.
Customizable Keycaps
A complete set of durable Dye-sublimated PBT keycaps featuring a two-tone grey base set along with 12 accent colour keycaps in blue, red and orange are included in the box with every keyboard.
Magnetic Hall-Effect Switches
Keychron Ultra-fast Lime Magnetic Switches feature pressure-sensitive Hall effect sensors and a pre-luber double rail system for ultra-smooth linear keystrokes.
Low Latency 8K Polling
Continuously detects key position to reset the moment you lift - no need to release fully enabling ultra-fast, precise repeated inputs.
Profile Toggle Switch
Swap between two customizable profiles on the fly via toggle switch.
RGB Backlighting
Vibrant RGB is fully customizable through the online web software with impressive per key RGB and a wide range of effects and settings that are saved to the onboard profiles.
Online Web Launcher
Use the ONEofZERO Web launcher app for effortless actuation point customization, Hall-effect functions, key remapping, macro assignment, shortcuts, and more.
Adjustable Actuation
Set per key actuation between 0.1mm and 3.35mm with 0.01mm sensitivity.
Dynamic Rapid Trigger
Continuously detects key position to reset the moment you lift - no need to release fully - enabling ultra-fast, precise repeated inputs.
Last Keystroke Prioritization
Favours last key press and deeper inputs when keys overlap to prioritize meaningful keypresses enabling smooth and intentional strafing.
Analog Mode
Hall effect sensors detect the depth of each key press translating into variable movement speeds.
Multi-Action Keystroke
Assign up to 4 distinct actions per key based on actuation distance.
Windows and iOS compatible
Swap between Windows and iOS with a quick key shortcut (Fn+CAPS LOCK).
SILICORE
Where Form Meets Function
Modular Silicone Ecosystem
The Si75-HE’s modular silicone ecosystem enhances acoustics and feel while introducing a new layer of visual expression through customizable, interchangeable components.
- Customizable Keycaps, Dampening Layer & Feet
- Silicore Modular Silicone Ecosystem
- Frosted Transparent Case
Every keyboard includes all accent colours in the box, allowing you to mix and match with all silicone options.
A complete set of two-tone grey keycaps comes stock, providing an understated base layer.
Features pressure-sensitive Hall Effect sensors and a pre-lubed double-rail system for ultra-smooth linear keystrokes.
Painted white aluminum plate provides stable switch alignment essential for Hall Effect sensors.
A porous foam layer between the plate and PCB absorbs resonance, reducing hollowness and improving sound quality.
- South-facing RGB LEDs
- Hot-swap compatible with all north-pole-facing Hall Effect switches (KS-20)
- Powerful MCU for ultra-fast inputs and response times
- Screw-in stabilizers for optimized typing feel
A soft PU foam paired with a rigid backing film that controls resonance, reducing ping and hollowness while producing a tighter, rounder sound profile.
From dampening pads to removable feet, gasket strips, and rotary knobs, each silicone component is part of a cohesive system designed for enhanced typing comfort and effortless customization.
Additional expansion packs are available online.
Frosted transparent ABS upper and lower case allow for a subtle pop from the silicone components within.
