    Modernized Elegance

    A seamless aluminum enclosure featuring no branding, thin side bezels, and an optional winkeyless top case for a vintage aesthetic — fit to be the centerpiece of any workspace. And the centered USB-C daughterboard provides a symmetrical setup with quick and inexpensive repairs.

    Multi Mounting

    Scarlet allows you to customize the way it feels and sounds by offering the two most popular mounting styles — top mount and gasket mount. It delivers a soft and comfortable typing experience, making the keyboard fade into the background so you can focus on creating your best work.

    Gasket mount.

    A silicone o-ring wraps around the plate and PCB, cushioning the keystrokes for a softer typing experience, and absorbing vibrations for a deep and quiet sound profile.

    Top mount.

    The switch plate is fastened to the top case with screws, delivering a distinct, tactile response. Complement the typing experience with the optional aluminum plate add-on.

    Multi-layout hotswap PCB.

    Designing a quick, simple, and beginner-friendly assembly process was made possible with kailh hotswap sockets without compromising on layout compatibility. One PCB supports both 6.25u and 7u spacebars, and double flex-slots provide a soft and cushioned typing experience when paired with a half-plate. All PCBs come with VIA Configurator compatible firmware installed out of the box.

    Ultra-soft POM plate.

    A matte black POM plate is included with each Scarlet kit, chosen for its deep, muted sound profile, and soft, flexible typing experience. An optional aluminum plate can be purchased for an enhanced tactile response while retaining the unique sound signature of the switches.
