The SayoDevice O3C is a small rapid trigger keypad with magnetic switches that reset the moment you lift, built for rhythm games and quick binds. A knob and a 0.96 inch color screen sit next to the keys for volume, shortcuts and live key stats.

Why it earns desk space

• Rapid trigger: keys reset as soon as you start lifting, so fast repeated taps register cleanly.
• Adjustable actuation: set the trigger point as short as 0.05 mm.
• 8000 Hz polling: reports to your PC at up to 8000 times a second over USB.
• Color screen: a 0.96 inch IPS display shows key travel and key counts, and the top line can show your own ID.
• Programmable knob: map it to any key, from volume to scrolling through a song list.
• Hot-swap switches: works with any magnetic switch and calibrates with a single click.

Specs

In the box

• 1 × O3C keypad

Good to know

• It's wired only and needs a USB connection.
• Recalibrate after you swap switches; it takes a single click.
• It's a keypad, not a full keyboard, so most people use it next to their main board.
