LTC Nimbleback NB831 75% Gaming Keyboard

The LTC Nimbleback NB831 is a compact 75 percent gaming keyboard with 81 keys and a built-in volume knob. It features hot-swappable sockets that accept both 3-pin and 5-pin MX-style switches. The keyboard connects wirelessly through 2.4 GHz or Bluetooth, and also works wired over USB-C while charging.

Gamers and typists who want switch freedom

This keyboard suits users who want to change switches without soldering and need a compact layout with a dedicated knob for media control. Buyers who require a full-size layout with a dedicated number pad or dedicated macro keys should look at a different form factor.

Hot-swappable PCB with MX-style compatibility

The single specification that decides fit is the hot-swappable PCB, which supports popular MX-style switches from brands such as Gateron and Kailh in both 3-pin and 5-pin variants. If you need a board locked to a single switch type or a non-hotswap design, this is not the right part.

Questions about this item

Will the 81-key layout and 2.4 GHz wireless link work alongside my existing USB keyboard and mouse without interference?

The 2.4 GHz dongle provides a dedicated wireless connection for the 81-key keyboard while your other USB peripherals remain on their own ports.

How can I confirm the hot-swap PCB and volume knob are functioning after I install my chosen 3- or 5-pin MX switches?

Press each key to register input in any text field and rotate or press the knob to adjust system volume or mute audio.

Does the box include keycaps and switches, or must I supply my own PBT keycaps and MX-style switches?

The keyboard ships with PBT keycaps and Red switches already installed; the hot-swap PCB lets you replace them later if desired.
