Teclado Keychron K2 Max Universal RF Wireless QWERTY Inglés Negro Gris 75 % Mecánico

The Keychron K2 Max is a 75% wireless mechanical keyboard with a compact 84-key QWERTY layout in black and grey. It supports 2.4 GHz RF, Bluetooth 5.1 and wired connections, offers south‑facing RGB backlighting, OSA double‑shot PBT keycaps, screw‑in PCB stabilizers and an ARM MCU with 256 KB flash for advanced customization.

Advantages

The K2 Max provides multiple connection modes (2.4 GHz, Bluetooth and wired) and a high 1000 Hz polling rate on 2.4 GHz and wired modes for low latency. It supports QMK firmware and the Keychron Launcher web app for key remapping and macros. The keyboard includes layered acoustic foams (IXPE, PET, EPDM) and a steel plate to improve typing sound and feel, plus optional hot‑swappable sockets compatible with most 3‑pin and 5‑pin MX‑style switches. Additional features include south‑facing RGB, OSA profile double‑shot PBT keycaps, screw‑in stabilizers and three adjustable typing angles.

• Office work and productivity on macOS and Windows (system toggle and extra keycaps included)
• Gaming with low latency using 2.4 GHz or wired modes
• Custom keyboard enthusiasts who remap keys or use QMK/Keychron Launcher
• Users who want to hot‑swap switches or install alternative stabilizers and keycaps

How to use

Choose a connection mode (2.4 GHz dongle, Bluetooth pairing or USB wired) and switch system mode between macOS and Windows if needed. Install the Keychron Launcher web app or flash QMK to remap keys and program macros. If you have the hot‑swappable model, remove keycaps and pull out switches with a switch puller to replace them with compatible 3‑pin or 5‑pin MX‑style switches. Use the function shortcuts and built‑in controls to adjust RGB settings, polling rate and saved layouts.

Recommendations

For stable gaming performance use the 2.4 GHz connection with the included dongle or wired mode for the lowest latency. When customizing, back up profiles before flashing firmware. Use screw‑in stabilizers and OSA PBT keycaps to maintain consistent typing feel and reduce key wobble.
