REDRAGON CASTOR K631 PRO: Features
- The REDRAGON Castor K631 Pro is a standout keyboard with a stunning design and RGB backlighting that can brighten any workstation.
- Outemu Red (Linear) switches are gentle, silent, and assist in preventing finger stress.
- This 68-key keyboard is 65% the size (or 35% smaller than) ordinary desktop keyboards, making it practical with lots of room for mouse movement on your desk and portable (473g) to carry almost anywhere—a wonderful complement for FPS gamers.
- The Redragon Castor K631 Pro RGB Mechanical BT + Wireless + Wired Keyboard’s unique socket design makes switch mounting easier and less wobbling, making 98%+ of the keys hot-swappable.
- Also, almost all market switches, whether they have 3 or 5 pins, can be put in without using a soldering iron.

The Castor K631 Pro from Redragon features three connectivity choices to meet your needs. Wireless mode uses a tiny 2.4GHz USB receiver to connect to your laptop or PC without wires. Use it with your phone or tablet? No problem—Bluetooth (v3.0/v5.0) permits pairing with all Bluetooth-enabled devices. For zero-lag arena access, go wired. The keyboard’s USB-C port charges built-in batteries and connects to all modern phones, tablets, and laptops.
Additionally, it includes a USB-C to USB-A 2-in-1 cable for computers without USB-C ports. Finally, the software-controlled RGB adds style to the class. You may customise the 20 built-in backlighting styles or sync them to your music for a discotheque vibe on your workstation. Macro shortcuts and key bindings can be put into the software for more efficient work and gaming.
