About

Sayo KB03 / KB04 are high-performance one-handed keypads designed for gamers who demand speed, precision, and full control. The KB03 features a compact 3-key layout, while the KB04 offers an expanded 4-key setup for enhanced input flexibility.

Powered by Hall Effect magnetic switches and Rapid Trigger technology, both models deliver ultra-fast actuation and instant reset for consistently accurate inputs—perfect for fast-paced gameplay.

With adjustable actuation in precise 0.05mm increments, every key can be fine-tuned to match your exact playstyle. The built-in display and control dial allow real-time adjustments without the need for software or web tools—even during gameplay.

A 1000Hz polling rate ensures stable, low-latency performance, while the CNC-machined 6063 aluminum top case provides a premium, durable feel. The acrylic base enhances RGB lighting with a smooth, diffused underglow for a clean and modern desktop aesthetic.

Fully programmable via VIA, both keypads support custom key mapping and multiple layers, with all settings saved directly onboard. The integrated 4-way joystick (with press-to-confirm) enables fast navigation and intuitive control.
