One-Handed 39-Key Macro Keypad

The Koolertron MG4AE-GAMAG39G-BLA is a single-handed mechanical keypad with 39 fully programmable keys and a clicky switch feel. A rotary knob adds three programmable inputs: left turn, right turn and press. RGB backlighting is configurable per key.

Suits users who need a compact macro layer

Designers, editors, programmers and gamers who want dedicated shortcuts for CAD, video, code or game skills can map each key and the two illuminated round buttons to any standard 104-key function, multimedia command or multi-step macro with .5-second delays. Four onboard configuration layers store setups without software running. Builders who need a full-size keyboard or a standard numpad should look elsewhere.

PS/2 interface with onboard MCU storage

The keypad connects via PS/2 and stores all 32 macro keys plus the four configuration layers in its built-in MCU, so programmed layouts persist across reboots and on any PC without driver installation.

Questions about this item

How do I verify the programmable knob and all 39 keys are functioning after plugging in the keypad?

Open the supplied programming software, assign a simple macro or media command to the knob rotation and press, then test each of the 39 keys and two illuminated round buttons to confirm they trigger the expected action.

What accessories are included in the box and what must I source separately?

The package contains the 39-key keypad, a USB cable, a keycap puller, 64 top-printed keycaps and 23 blank keycaps; no additional items are required for basic operation.

Which version should I choose — the 39-key, 45-key or 48-key model?

Select the 39-key model if you need a compact single-handed layout with a programmable knob and 32 macro buttons; the 45-key and 48-key variants add extra keys but share the same programming engine and four-layer configuration storage.
