Description

🧠 Expert Features – For the Typing Jedi and Macro Wizards

  • Tri-Mode Connectivity: Switch between 2.4 GHz (1000 Hz polling rate), Bluetooth 5.1 (connects to 3 devices), and wired Type-C. One board to rule all your platforms.
  • QMK + VIA + Keychron Launcher Support: Full key remapping, macros, and shortcut creation made easy via open-source firmware and an intuitive web app (wired mode required).
  • Hot-Swappable (Optional): Swap your switches in seconds—compatible with most 3-pin and 5-pin MX-style switches. No soldering, just click and go.
  • Keychron Super Banana Switch: Linear, buttery, and built for speed with up to 50 million clicks lifespan. Includes transparent top housing for brighter RGB goodness.
  • Acoustic Foam Layers (IXPE, PET, EPDM): Dampens clacks, refines the thock—making your keystrokes sound as good as they feel.
  • South-Facing RGB Backlight: Better RGB visibility for the typist, 22+ lighting modes, and zero interference with Cherry-profile caps.
  • Double-Shot PBT Keycaps (OSA Profile): Comfortable, spherical keycaps that resist shine, sweat, and smudges.
  • Ergonomics Dialed In: Three typing angles (5°, 9°, 12°) and a 75% layout with minimal desk footprint.
  • Multi-System Support: Toggle switch for macOS/Windows plus extra keycaps for both OS. Dual layout memory included.
  • Steel Plate + PCB Screw-In Stabilizers: Sturdier typing, less wobble, and better feedback—especially on larger keys.
  • Massive Battery Life: 4000 mAh battery delivers ~190 hrs with backlight off and ~100 hrs with RGB at low brightness.
  • Built for Developers: With a 32-bit ARM Cortex-M4 STM32F402 MCU and 256KB flash, it’s perfect for coding and customization projects.
