This meticulously designed PCB is the foundation for building a low-profile, ortholinear, column-staggered ergonomic keyboard that rivals the comfort and efficiency of premium boards like the ZSA Voyager, but at a fraction of the cost. Oh, and did I mention it's open source, too?!

Ergonomic Design: The ortholinear layout and column stagger promote natural hand and wrist positioning, reducing strain and fatigue during extended typing sessions.

Low-Profile Comfort: Designed for Kailh Choc V1 switches, the Mantaray2040 offers a sleek, ultra-portable form factor without sacrificing key feel.

Customization at Your Fingertips: Hot-swappable sockets allow you to experiment with different Choc V1 switches to find your perfect tactile or linear experience.

Powered by QMK: Fully compatible with QMK firmware, giving you complete control over keymaps, macros, and lighting effects.

OLED Display: Integrate a 128x32 OLED screen for real-time information, custom graphics, or just to add a touch of personality to your build.
