Non-shine Through PBT Keycaps & RGB Backlit: Designed for premium type feeling, the K3 Pro comes with our unique double-shot PBT keycaps that made of durable non-backlight shine through PBT material with excellent oil resistance for long-term use. Comes with more than 22 types of RGB backlight settings. Hot-swappable Support: The pre-installed low-profile mechanical tactile brown switch provides unrivaled tactile responsiveness with up to 50 million keystroke lifespan. You can easily hot-swap every low-profile Gateron mechanical switch in a few seconds to customize the typing experience without soldering. Note: The K3 Pro is currently compatible with Gateron low-profile mechanical switches only, as QMK does NOT support low-profile optical switches. Supports Wireless and Wired Mode: You can connect the K3 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking across your laptop, phone, and tablet. Switch among them swiftly. The K3 Pro can last up to 100 hours (at backlit off) with a 1550 mAh battery. It also has USB Type-C wired mode with 1000 Hz polling rate (Wireless: 90 Hz). With QMK and VIA Support: Keychron K3 Pro allows anyone to remap any key, and create macro commands, shortcuts, or combination keys through VIA. Simply connect the K3 Pro to your device with a cable, drag and drop your favorite keys or macro commands to remap any key you want on any system (macOS, Windows, or Linux). Ultra-slim Wireless Custom Mechanical Keyboard: The K3 Pro is the first low profile wireless mechanical keyboard with QMK/VIA enabled for endless possibilities. Anyone can master any keys or macro commands on its 75% compact layout through VIA. It has included LSA (low profile spherical-angled) profile keycaps for both Windows and macOS.
