Compact three-key macro keypad

The iC SayoDevice O3C is a compact macro keypad built around three Hall-effect magnetic linear switches. It targets rhythm-game players and streamers who need rapid, adjustable actuation for titles such as OSU and Geometry Dash. A 0.96 inch IPS colour screen and a rotary knob add visual feedback and volume control in a 2.4 by 3.96 by 1.3 inch USB-powered package. The keypad runs at an 8000 Hz polling rate over a Type-C USB 2.0 connection.

Verify USB port and calibration routine

Ensure your system has a free USB Type-C or USB-A port for the supplied cable; the device draws power directly from the bus. Before first use or after any firmware update the keypad requires a manual calibration step, so allow time for that setup. The hot-swappable sockets accept any compatible Hall magnetic switch, letting you replace the pre-installed Outemu Pink units without soldering. Custom key mappings and knob functions are configured through the companion software on a PC.

Suits rhythm gamers and macro users.

This keypad suits rhythm-game enthusiasts who want per-key trigger adjustment down to 4.000 mm and a high polling rate for low-latency input. Streamers needing a dedicated macro cluster with a volume roller and a tiny status display will also benefit. It is not for users who need a full alphanumeric keyboard, a numeric keypad, or multi-device wireless connectivity. Buyers who require more than three programmable keys should look at larger macro pads.

Questions about this item

Does the box include everything needed to start using the O3C or must I buy extra switches or keycaps?

The unit ships with three Outemu Pink Hall magnetic linear switches already installed, a volume knob, a 0.96 in IPS colour screen and a USB Type-C cable; no additional switches or keycaps are required unless you want different feel or style.

The listing mentions Outemu Pink switches — how do I decide whether that version suits my rhythm-game playstyle?

Outemu Pink Hall switches are linear magnetic switches with a 0–4.000 mm adjustable actuation point and rapid-trigger support, so you can set a very short travel for fast OSU or Geometry Dash tapping.

What does the 8000 Hz polling rate actually do when the keypad is plugged into a PC?

An 8000 Hz report rate means the keyboard sends input data to the PC up to eight thousand times per second, reducing latency so each key press in rhythm games registers with minimal delay.
