GravaStar Mercury V75 HE

Engineered for intense esports competition and tactile luxury, the GravaStar Mercury V75 HE elevates the magnetic keyboard formula with an industrial, futuristic aesthetic. Unlike lightweight plastic keyboards, the V75 HE employs a semi-aluminum construction. A die-cast metal frame forms a rigid structural backbone that resists flex during aggressive keystrokes, paired with a sculpted polymer base and dual-zone ambient side lighting to deliver a battle-ready command station look.

Underneath the hood, the Mercury V75 HE leverages Hall Effect magnetic sensor technology paired with 256kHz internal scanning. Because inputs are triggered via electromagnetic induction rather than physical metal contacts, mechanical switch bounce and contact degradation are eliminated. Gamers can customize the actuation point from a shallow 0.1mm hair-trigger to a deliberate 3.5mm bottom-out depth in 0.1mm steps. Combined with Dynamic Rapid Trigger (RT), keys reset instantaneously upon upward release, giving tactical FPS players (Valorant, CS2, Apex Legends) zero-delay counter-strafing and instantaneous stop-fire capability. It also incorporates Last Keystroke Prioritization (LKP) and Snap Click (SOCD) logic to streamline directional peeking.

Acoustic tuning and typing feel match custom enthusiast keyboards. Built around an aluminum switch plate and a cushioned gasket-mount system, the keyboard integrates a 5-layer acoustic dampening matrix comprising PORON sandwich foam, an IXPE switch pad, a PET sound-dampening sheet, PORON base foam, and a molded silicone bottom layer. This internal dampening absorbs vibration, eliminates metallic ping, and delivers a clean, thocky acoustic profile. The board connects over a high-speed wired USB-C connection reporting at a true 8000Hz polling rate (0.125ms response time).

Key Features

• True 8000Hz Polling Rate: 8K USB polling with 256kHz key scanning slashes input latency to 0.125ms for frame-precise reaction times.

• Semi-Aluminum Exoskeleton: Combines a die-cast aluminum metal top frame for rigidity with a modern polymer base and dual-zone RGB ambient lighting.

• Hall Effect Linear Switches: Contactless magnetic switches with 0.01mm sensitivity and hot-swappable compatibility for supported Gateron and TTC magnetic switches.

• Adjustable Actuation & Rapid Trigger: Set trigger depths between 0.1mm and 3.5mm, paired with Dynamic Rapid Trigger for instant key resets.

• LKP & Snap Click (SOCD): Advanced firmware prioritizes opposing directional inputs for tournament-grade counter-strafing.

• 5-Layer Acoustic Gasket Structure: PORON foams, IXPE switch padding, PET film, and silicone dampeners minimize resonance for a clean typing sound.

• GravaStar GS Hub Software: Browser and desktop driver support for configuring per-key actuation curves, macros, and RGB illumination.
