Teclado mecânico 80% QWERTY Keychron Q3 Ultra 8K — Bluetooth e com fios, retroiluminação RGB, preto

The Keychron Q3 Ultra 8K is an 80% mechanical QWERTY keyboard combining wireless and wired connectivity in a compact straight 80% form factor. Built with an all-metal 6063 aluminum frame and a PC backplate, the keyboard delivers a durable and stable chassis with a refined finish. It supports Bluetooth 5.3, 2.4 GHz wireless and wired USB connection, offers an 8000 Hz polling rate in wired and 2.4 GHz modes, per-key RGB backlighting with multiple effects, and hot-swappable MX-style switch compatibility for straightforward customization.

Advantages

The Q3 Ultra 8K provides a long battery life of up to 660 hours (with backlight off) and multi-device Bluetooth pairing for easy switching between computer, phone and tablet. Acoustic foam layers, double-gasket construction and an internal acoustic pad reduce resonance and produce refined typing acoustics. Pre-lubed Keychron Silk POM switches and KSA profile double-shot PBT keycaps deliver smooth, durable keystrokes and resistance to shine. Extensive programmability through the Keychron Launcher and an MCU with 1MB flash enable firmware flexibility and custom keymaps.

How to use

Charge the keyboard via the provided USB cable and pair with devices using Bluetooth 5.3 or connect via 2.4 GHz dongle or wired USB for lowest latency. Use the system toggle and extra keycap set to switch between Windows and macOS layouts or save two layout profiles on the keyboard. Install and open the Keychron Launcher web app to remap keys, create macros and adjust lighting. For hardware customization, hot-swap switches without soldering and, if desired, remove or adjust the acoustic pad to alter typing flexibility and sound.

Recommendations

For the best balance of battery life and visual feedback, disable or lower RGB brightness during extended unplugged use. Use the 2.4 GHz or wired connection when minimal input latency is critical (competitive gaming). When customizing switches or stabilizers, work on a clean surface and keep screws and small parts organized to maintain the keyboard's acoustic and structural integrity.
