Compact 65% Layout

The LTC NB681 Nimbleback is a wired 65% mechanical gaming keyboard with 68 keys including dedicated arrow and navigation keys. It uses hot-swappable Brown switches that provide tactile feedback without an audible click. The compact footprint saves desk space while keeping essential controls within reach.

Hot-Swappable Brown Switches

This keyboard replaces fixed-switch boards by letting you swap any MX-style three-pin or five-pin switch without soldering. The upgrade is worthwhile when you want to experiment with different tactile, linear or clicky switches or when a single switch fails and you prefer to replace only that switch. On-board RGB lighting offers 18 preset modes with five brightness and speed levels.

USB Passthrough and Compatibility

Check that your system has a free USB Type-C port or a USB-A port with an adapter for the 1.8 m cable. The keyboard includes two USB 2.0 passthrough ports for a mouse, flash drive or phone charging. It supports Windows 7 or later, macOS and iOS without additional drivers. No palm rest is included.
