All-Around Customizable Keyboard - Every component has been conveniently assembled so you can customize and adjust every part the way you want. Programmable Knob - Designed to enhance your creative workflow, the premium rotary encoder allows you to customize your favorite keys and macros through the innovative VIA software with ease. You can easily customize the V1's knob to your desired key or macro commands like zooming in/out, adjusting screen brightness, brush size, volume, selecting video clips or photos, or backlight hue.
Double-Gasket Design - The gasket design provides the board with a nice, flexible typing feel and a satisfying typing sound. In addition to the gaskets on the plates, the Q2 features silicone pads between the top and bottom cases to significantly reduce the sound resonance between the metals and reduce the noise of the impacted metals. Hot-Swappable PCB - The V1 hot-swappable PCB allows you to easily swap out switches without disassembly and de-soldering, so you can use your favorite switches or try out new switches without the risk of damaging the keyboard. The PCB supports both 3 pin and 5 pin MX mechanical switches.
South Facing RGB - A unique RGB feature where the LEDs are located at the bottom of the switch rather than the top, which make them appear brighter because they are facing the typer. The south-facing RGB is also free from interference when the users install OEM or Cherry-profile alternative keycaps on the keyboard. Sound Absorbing Foam - The V1 features a sound absorbing form that reduces vibration and drastically improves sound signature.
Mac OS and Windows Support - Built with the Mac users experience in mind while still retaining compatibility for Windows devices. It also allows you to save two different layouts in the keyboard, one for each system. QMK and VIA Support - With full QMK and VIA support, you can program and remap each key on the keyboard with ease. The open-source firmware means endless possibilities for keyboard layouts, shortcuts, backlight effects, and more.
