Compact 75% layout with 84 keys

The LTC Nimbleback NB841 PRO is a 75% wireless mechanical gaming keyboard with 84 keys and linear switches. It includes a built-in display screen, a rotary volume knob and triple connectivity over 2.4 GHz wireless, Bluetooth and USB-C wired. Hot-swap sockets accept most 3-pin and 5-pin MX-style switches without soldering.

Sustained typing and gaming sessions

The triple-layer silicone dampening structure reduces hollow resonance and cavity noise during long periods of use. Oil-resistant PBT keycaps maintain surface texture and resist shine over time. The hot-swap PCB allows switch replacement without downtime, keeping the board in service without soldering work.

Thermals, noise and power draw

The keyboard draws power through the USB-C wired connection or its internal battery when used wirelessly. The silicone dampening layers suppress keystroke clatter for a quieter profile in shared spaces. The display and RGB lighting are adjustable via the knob or software to manage battery consumption during normal use.

Questions about this item

How loud is the 75% keyboard with its 3-layer silicone dampener during all-day typing?

The triple-layer silicone structure cuts hollow resonance and cavity noise, while oil-resistant PBT keycaps add a muted, smooth feel for extended sessions.

Which devices and cables do I need to use the 2.4 GHz, Bluetooth and USB-C wired modes?

A USB port for the 2.4 GHz dongle, a Bluetooth host, or a USB-C cable for wired operation — all three are built into the board.

Can I keep my existing MX-style switches and keycaps when I move to this 84-key hot-swap PCB?

Yes, the PCB accepts most 3-pin and 5-pin MX-style switches such as Gateron or Kailh, and standard PBT keycaps fit the 75% layout.
