Redragon K742 specifications and in-depth review

Redragon K742

Manufacturer: Redragon

The Redragon K742 is a full-size mechanical gaming keyboard built around a gasket mount construction that sits within a plastic and aluminum chassis. It supports wireless use through both Bluetooth 5.0 and a 2.4GHz connection, alongside a wired USB option, giving users flexibility in how they connect. The keyboard ships in black, white, or gray colorways and includes RGB backlighting with south-facing LEDs, adjustable feet, and a detachable cable. At 850 g and with dimensions of 394 x 144 x 39 mm, it occupies the footprint of a standard full-size layout while trimming down to a 98% form factor.

On the switch side, the K742 uses RPC Linear mechanical switches with a 2 mm actuation distance, 40 g actuation force, and 3.6 mm total travel, and the board supports hot-swapping so switches can be replaced without soldering. Keycaps are double-shot PBT in an OEM profile on a standard ANSI layout, with media functions accessible via the Fn key and a rotary dial included for quick adjustments. The keyboard carries QMK support and full N-key rollover, while the onboard battery is rated for up to 53 hours of use. A one-year warranty is included.

Pros
  • Hot-swappable switches allow for easy switch replacement without soldering
  • Tri-mode connectivity via Bluetooth 5.0, 2.4GHz wireless, and USB offers flexible setup options
  • Gasket mount construction provides a softer, more cushioned typing experience
  • 53-hour battery life reduces how often the keyboard needs to be charged
  • QMK support enables deep firmware customization for layout and macro configuration
  • N-key rollover ensures every simultaneous keypress is registered accurately
Cons
  • No VIA support limits on-the-fly remapping without flashing firmware
  • Media functions are only accessible through the Fn key rather than dedicated keys
  • No wrist rest is included in the box
  • The keyboard is not designed for Mac, limiting out-of-the-box compatibility for macOS users
  • Lacks rapid trigger and adjustable actuation, which are relevant features for competitive gaming use cases
Who is this for?

This keyboard suits users who want wireless flexibility without sacrificing customization, thanks to its tri-mode connectivity and QMK firmware support. The gasket mount and hot-swappable linear switches make it a solid fit for typists and enthusiasts who enjoy tuning their board over time. Its 53-hour battery life also makes it a practical choice for those who prefer a cable-free desk setup and do not want to charge frequently. The full 98% layout with a rotary dial appeals to users who want a near-complete key set in a slightly more compact footprint.

Who is this NOT for?

Users who rely on rapid trigger or adjustable actuation for competitive gaming will find those features absent here, making it less suited to that specific use case. The lack of VIA support means users who prefer on-the-fly remapping without reflashing firmware may find the customization workflow inconvenient. Additionally, those seeking a Mac-compatible keyboard out of the box or users who require dedicated media keys for quick access during content work may find the layout and platform support limiting.
