Highlights
- Smart 0.85-Inch TFT Screen & Metal Knob: Equipped with an interactive color display that provides real-time tracking for battery capacity, time and date, current OS mode, and connection types. The adjacent CNC metal knob lets you scroll system configurations or adjust lighting profiles, while an "FN + press" shortcut drops you right into direct volume management.
- Upgraded Gasket-Mount & Slotted PC Plate: Built around a structural gasket assembly paired with a horizontally slotted Polycarbonate positioning plate. This eliminates harsh metal-on-metal impacts, softening keystrokes and ensuring highly uniform feedback across the entire typing surface.
- 1.2mm FR4 Single-Key Slotted PCB: Outfitted with a premium, dual-layer FR4 circuit board engineered with precision flex cuts tracking around each individual key switch. These dedicated micro-slots deliver consistent flexibility, preventing hand strain during heavy coding, typing, or long gaming marathons.
- Five-Layer Acoustic Dampening Cavity: Layered internally with five specialized sound-absorbing materials: PORON sandwich cotton, IXPE switch pads, PET noise-cancellation films, Japanese DEPDM foam, and molded silicone base padding. This advanced sound matrix captures hollow pitch echoes, converting standard typing into a clean, deep, and "thocky" sound signature.
- Full-Key 3/5-Pin Hot-Swap Sockets: Designed with universal hot-swappable pin sockets that support quick changes between your favorite 3-pin and 5-pin mechanical switches. Change out switches instantly without ever pulling out a soldering iron to easily curate your personalized tactile environment.
- Pre-Lubed Premium Linear Switches: Arrives pre-configured with factory-lubricated linear switches (such as the quick-response Shark Switch or resonant Gift Switch). These premium stems travel flawlessly straight out of the box, combining clean actuation thresholds with smooth travel dynamics.
- Hyper-Speed Tri-Mode & 4000mAh Power Core: Enjoy total wireless freedom across multiple devices. Connect via high-stability 2.4GHz wireless with low latency, pair over Bluetooth 5.0 for multi-device multitasking, or use a secure USB-C wired connection. A massive 4000mAh lithium battery handles extensive wireless play sessions on a single charge.
- South-Facing RGB LEDs & Driverless QMK Web Configurator: Features vibrant south-facing RGB LEDs with dynamic lighting presets that avoid keycap binding issues. Mapping key layouts, building intricate macros, or updating your favorite custom GIF animations for the TFT screen is made simple via the browser-based cloud web driver (qmk.top)—no bulky software downloads required.
Elevate your desktop setup and typing precision with the ATTACK SHARK X820 Ultra Mechanical Keyboard in Moonlight. Blending a space-saving 75% layout, five-layer noise-dampening engineering, hot-swappable switch sockets, and a smart color TFT screen, this beautiful tri-mode keyboard provides the ultimate combination of tactile performance, effortless device multitasking, and clean hardware styling.
