ONEofZERO - Si75-HE Hall-Effect Keyboard

The ONEofZERO Si75-HE, powered by Keychron, combines high-performance Hall Effect technology with a refined typing experience and modular customization. Built around ONEofZERO's Silicore design framework, it features a gasket-mounted structure, frosted transparent case, Keychron Lime magnetic switches, 8K polling, adjustable actuation, Dynamic Rapid Trigger, and extensive web-based customization.

Designed to balance performance, comfort, and aesthetics, the Si75-HE gives you precise control over how your keyboard responds, feels, sounds, and looks.

Key Features

• Keychron Lime Magnetic Switches: Ultra-fast linear Hall Effect switches feature pressure-sensitive sensing and a pre-lubed double-rail design for smooth, stable keystrokes.
• 8K Polling Rate: High-speed polling provides fast and responsive input for demanding applications.
• Adjustable Actuation: Fine-tune individual key actuation from 0.1mm to 3.35mm with adjustments as precise as 0.01mm.
• Dynamic Rapid Trigger: Continuously detects key position, allowing keys to reset as they're released rather than requiring them to return to a fixed reset point.
• Last Keystroke Prioritization: Prioritizes the latest and deeper input when opposing keys overlap for more intentional directional control.
• Analog Mode: Hall Effect sensors detect how far a key is pressed, enabling variable input based on key travel.
• Multi-Action Keystrokes: Assign up to four different actions to a single key based on actuation distance.
• Dual Onboard Profiles: A dedicated toggle switch lets you quickly switch between two customizable profiles.
• Customizable RGB Backlighting: Per-key RGB lighting offers a wide range of effects and settings that can be saved to onboard profiles.
• ONEofZERO Web Launcher: Customize actuation points, Hall Effect functions, key mappings, macros, shortcuts, RGB lighting, and more through the online configuration software.

Silicore Modular Design

ONEofZERO's Silicore system uses internal silicone components to help refine the keyboard's acoustics and typing feel while adding a distinctive visual element through the frosted chassis.

The Si75-HE is available in Blue, Red, and Orange, allowing you to choose the colour that best complements your setup.

Gasket-Mounted Construction

Silicone strips isolate the plate and PCB from the upper and lower case, helping reduce vibration while creating a softer, more controlled typing feel and sound profile.

Frosted Transparent Case

The translucent ABS chassis subtly reveals the coloured internal silicone components, creating a unique layered aesthetic while maintaining a clean, modern appearance.

Dye-Sublimated PBT Keycaps

The Si75-HE features a complete set of durable dye-sublimated PBT keycaps with a two-tone grey colourway and accent keys that complement the keyboard's design.

Available Colours

• Blue
• Red
• Orange

Compatibility

• Windows
• macOS
• Switch between operating system modes using Fn + Caps Lock
