Description

Product Highlights

This keyboard stands out in the market due to its southpaw 1800 layout, which positions the numpad on the left side—a rare feature that benefits left-handed users and those seeking a unique ergonomic arrangement. The keyboard is engineered with a solid 6063 aluminum case, giving it a substantial weight of approximately 4.2kg when fully built, ensuring stability during intense typing or gaming sessions. The inclusion of a 7° typing angle promotes comfortable hand positioning, reducing fatigue over long periods of use. The mounting system is highly versatile, supporting both top mount and silicone bottom with gasket options, as well as plateless configurations for a tailored typing feel. The PCB is fully compatible with QMK and VIA, enabling users to remap keys, create macros, and adjust functionality to suit their needs. These features collectively make the keyboard a compelling choice for users who demand both form and function in their daily computing experience.

Construction Details

The keyboard boasts a striking aesthetic, characterized by its retro-inspired design and robust build quality. The case is precision-machined from 6063 aluminum, offering both durability and a premium tactile feel. An inner brass weight, treated with an antioxidant finish, adds to the keyboard’s heft and stability, ensuring it remains firmly in place during use. The ANSI layout standard is maintained, providing familiarity for most users while integrating the unique southpaw numpad placement. The keyboard’s surface finish is smooth and refined, with attention to detail evident in every aspect of its construction. The 7° typing angle is carefully chosen to promote ergonomic comfort, while the overall design supports long-term durability and resistance to wear. The build quality is further enhanced by the option to use either a top mount or a silicone bottom with gasket, allowing users to fine-tune the typing experience to their preference.

Cross-Platform Compatibility

This keyboard is designed for wired connectivity, ensuring a stable and lag-free connection ideal for both gaming and professional use. The wired-only configuration eliminates the need for batteries or charging, providing uninterrupted performance during extended sessions. The keyboard connects via a standard USB interface, making it compatible with a wide range of devices, including Windows, macOS, and Linux systems. Thanks to its QMK and VIA support, users can easily switch between different operating systems without losing access to their custom keymaps or macros. The plug-and-play nature of the USB connection means setup is straightforward, requiring no additional drivers or software for basic operation. For advanced customization, the open-source QMK and VIA platforms provide cross-platform support, allowing users to program and update the keyboard’s firmware regardless of their preferred operating system. This ensures that the keyboard remains versatile and adaptable, whether it’s used in a gaming rig, a creative workstation, or a multi-device office environment.

Flexible Programmability

Personalization is at the heart of this keyboard’s design. With full QMK and VIA support, users can remap any key, create complex macros, and adjust layer functions to suit their workflow or gaming needs. The open-source nature of these platforms means there are virtually no limits to customization, from simple key swaps to advanced scripting for automation. Users can also configure multiple layers, enabling quick access to shortcuts, media controls, or application-specific commands. For those who value visual customization, the keyboard supports customizable backlighting (if equipped with compatible switches and LEDs), allowing users to tailor the lighting effects and colors to match their setup or mood. The VIA software provides an intuitive graphical interface for real-time programming, making it accessible even to those new to keyboard customization. Advanced users can dive deeper into QMK’s powerful features, including tap-dance, mod-tap, and custom firmware builds. This level of programmability ensures that the keyboard can evolve with the user’s needs, offering a truly personalized typing experience.

Beyond Basics

In addition to its core features, the keyboard includes several thoughtful extras that enhance the user experience. The substantial brass inner weight not only adds to the keyboard’s stability but also contributes to a satisfying acoustic profile. The option for plateless mounting allows for a softer, more flexible typing feel, catering to users who prefer a unique tactile response. The keyboard’s retro-inspired aesthetic sets it apart visually, making it a standout piece on any desk. While it does not include wireless connectivity or USB pass-through, its focus on build quality, customization, and ergonomic innovation makes it a compelling choice for enthusiasts seeking more than just a standard keyboard.
