Corne V4.1 Procyon Split Mechanical Keyboard Kit — Square Touchpad, Mouse Knob, Custom RGB VIA, Hot-Swappable MX Switches, Wired Single Mode, FDM Printed Shell Split Keyboard

Touch module & compatibility: The touchpad uses the I2C protocol and connects directly to the motherboard with no extra drivers required. It works with Windows, macOS and Linux and is optimized for large-scale cursor movement for smoother pointer control. Knob & interaction: The rotary knob is built as an incremental encoder that emits one command per rotation, eliminating slip delay. Combined with the touchpad it enables a mix of precise positioning and fast scrolling. Materials & finish: The default enclosure is FDM-printed PLA with a matte texture. PETG is offered as an advanced option — it provides a 30% increase in impact resistance and is recommended for mobile office use. Slight surface layering is normal for 3D printing and to be expected. Lighting & customization: After the shaft body is installed, the keyboard defaults to a rainbow flow lighting mode. VIA support allows you to set single-key colors and adjust breathing rates. The board also supports "lighting up by level" (for example, keeping the main key area illuminated while only lighting functional regions when triggered).
