Koolertron 23-Key Programmable Gaming Keyboard White Red Axis RGB

SKU CH-4K4E-N5TW2

A compact 23-key mechanical keyboard with fully programmable keys, 24 macro slots supporting up to 792 commands, RGB lighting and four onboard profiles

  • All 23 keys freely programmable via dedicated software
  • 24 macro slots with up to 792 stored commands
  • Customizable RGB backlight with user-defined colours
  • Four onboard profiles saved in built-in MCU
  • Compact one-handed design supplements standard 104-key layout

Compact 23-Key Macro Keypad

The Koolertron 23-key programmable keyboard is a dedicated macro pad designed for gamers, video editors and programmers who need rapid access to complex shortcuts. Its small footprint keeps the main typing area clear while placing 23 fully programmable keys within easy reach of one hand.

USB HID Device with Onboard Memory

The keypad connects over USB and stores four distinct profiles in its built-in MCU, so no background software is required once macros are written. All 23 keys plus 24 macro slots supporting up to 792 commands are configured through the supplied Windows utility, freeing the host system from driver overhead.

Replaces Layered Shortcuts on Full-Size Boards

Users who currently bind macros to function layers on a 104-key keyboard gain instant, single-press triggers without chord combinations. The jump is worthwhile when workflows demand more than a dozen timed macros or when desk space rules out a second full-size deck. Not suited for buyers who need a primary typing keyboard or dedicated media jog wheels.

Questions about this item

How many layers of macro profiles can the onboard MCU store?

The built-in MCU stores four layers of programmed settings, so you can switch between different key layouts without re-uploading from the software.

Does the keyboard draw power from a single USB connection or need an external adapter?

It operates from a single USB cable; no separate power adapter is required for the RGB lighting or macro engine.

What operating system is needed to run the programming software?

The dedicated configuration software runs on Windows; macOS and Linux are not supported for key remapping or macro creation.
