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).You may also like Maxtek 10.4 mm Standard Clear CD Jewel Case with Assembled Black Tray - Single Disc 25-Pack.
