CORNE V4.1 Wireless Split Keyboard — 2.4G Single-mode, Ergonomic, Hot-Swappable PCB, Without Lights, 3D Printing Shell

CORNE V4.1 is a compact, split ergonomic keyboard built to reduce fatigue during long typing sessions. The classic split layout separates the board into two independent halves so you can set the spacing and tilt to match your shoulder width and sitting posture. This arrangement helps prevent wrist bending and shoulder strain caused by extended office work, programming, or heavy text input, making comfortable typing a reality rather than a slogan. The keyboard uses 2.4G single-mode wireless connectivity for a stable, cable-free setup. As a DIY-focused model, it emphasizes personalization: the hot-swappable PCB requires no soldering, so switches can be swapped or replaced quickly and easily — ideal for testing different switch types or performing maintenance, even for beginners. The shell supports 3D printing, letting you produce custom housings with your preferred shape, texture, and color to turn the board into a unique desktop piece. Full key remapping and advanced function setup are supported via VIAL’s open-source configurator, enabling visual programming of shortcuts, macros, and complete layout changes without diving into complex code. In short: ergonomic split design, wireless 2.4G single-mode, hot-swap convenience, 3D-printable casing, and full VIAL customization — all without built-in lighting.
