Compact Wireless Mechanical Keyboard

The BFKK Immersion A3 is a tenkeyless mechanical keyboard built for gamers and typists who want a low-profile layout without a numeric pad. It uses Kailh low-profile linear switches that are hot-swappable for easy customisation. An integrated display screen and 16.8 million colour RGB backlighting provide visual feedback and per-key lighting effects. The aluminium alloy frame keeps the profile slim while maintaining rigidity.

Triple-Mode Connectivity Frees Desk Space

Connect via Bluetooth 5.0, 2.4 GHz wireless or the Type-C USB cable to switch between up to three devices with dedicated on-board buttons. The 5800mAh battery delivers up to 50 hours of use on a single charge, reducing cable clutter during long sessions. Because the board is wired-capable, it works even when the battery is depleted. No separate receiver storage is required when using the wired or Bluetooth modes.

Software-Controlled Screen and Macros

The companion software lets you upload custom GIFs and images to the built-in display for personalised animations or system info. Programmable macros allow complex keystroke sequences to be assigned to any key. Anti-fade keycaps keep legends readable after extended use, and the hot-swappable sockets let you replace switches without soldering. The keyboard supports both Windows and macOS layouts.
