A trackball under each thumb. Wireless freedom. Ceramic precision bearings. Levels54 is a premium ergonomic split keyboard built for professionals who type all day and refuse to sacrifice their wrists.

Position each half at shoulder width. Scroll documents with your left thumb. Navigate with your right. Your hands never leave the keys, and your wrists stay neutral.

Built-In Trackballs: Ditch Your Mouse Forever

Each half of this ergonomic keyboard features a 34mm Perixx trackball riding on Silicon Nitride G5 ceramic bearings—the same material used in high-performance industrial equipment. The result: glassy-smooth cursor control that never skips, never sticks.

Left thumb: Scroll through documents, spreadsheets, code.
Right thumb: Point, click, drag.
Your mouse: Gathering dust.

The Nylon 11 SLS-printed carrier isn't just structural—it's tactile. You'll feel the quality every time your thumb touches it.

Premium Materials. No Compromises.

Every component is selected to make a split ergonomic keyboard that lasts, and feels like it.

316 Stainless Steel Switch Plates — Surgical-grade stainless. Rigid. Weighty. The foundation for a satisfying keystroke.

HT-PLA Cases — High-temperature PLA delivers dimensional stability without the brittleness of standard prints. Soft matte texture.

Ceramic Trackball Bearings — G5 Silicon Nitride. Industrial-grade smoothness. Zero maintenance.

Nylon 11 Components — SLS-printed power switches and trackball carriers. Precision-formed, chemically resistant, built to last.

Black Walnut Bottom (Limited Edition) — Real wood. Real weight. Real presence on your desk.

Fully Programmable. Infinitely Customizable.

Hot-Swap Everything — 54 MX sockets mean you can swap switches in seconds. Try linears. Try tactiles. Find your perfect feel without soldering.

ZMK + Studio — Remap every key, create layers, build macros—directly in your browser. No command line. No flashing tools. Just drag, drop, done.

VIK Expansion Ports — Both halves include VIK connectors for hardware expansion. Add OLED screens, sensors, rotary encoders, or modules that don't exist yet. This ergonomic keyboard grows with your needs.

Engineered to End Wrist Pain

Standard keyboards force ulnar deviation—the inward wrist bend that causes carpal tunnel syndrome. Every. Single. Day.

Split ergonomic keyboards fix this by design:

→ Shoulder-width positioning eliminates ulnar deviation entirely
→ Wireless freedom means you position each half exactly where your hands naturally fall
→ Built-in trackballs remove the constant reach-and-return motion that strains forearms
→ Ortholinear layout aligns keys with natural finger movement

If you type 8+ hours a day, this isn't a luxury. It's occupational health equipment.
