Product information

Description

The Keychron K3 Pro is a low-profile wireless mechanical keyboard with QMK/VIA support for advanced customization. It offers both wireless Bluetooth 5.1 connectivity for up to three devices and a wired USB Type-C connection with a 1000 Hz polling rate. The ultra-slim aluminum-body design uses low-profile Gateron mechanical switches and double-shot PBT keycaps for a compact, durable typing experience suitable for Mac and Windows users.

Advantages

Supports simultaneous connections to three devices via Broadcom Bluetooth 5.1 and swift device switching. QMK and VIA compatibility allow full key remapping and macro programming across macOS, Windows, and Linux. The keyboard is hot-swappable for low-profile Gateron mechanical switches, enabling easy switch replacement without soldering. Wired mode provides a 1000 Hz polling rate for minimal latency during competitive gaming. Included are keycaps for both macOS and Windows layouts, plus redesigned stabilizers and three adjustable typing angles for ergonomic support.

Key specifications

  • Connectivity: Bluetooth 5.1 (up to 3 devices) and USB Type-C wired
  • Customization: QMK & VIA support for key remapping and macros
  • Switch type: Low-profile Gateron mechanical switches (hot-swappable)
  • Polling rate (wired): 1000 Hz
  • MCU: ARM architecture with 128K Flash
  • Keycaps: Low-profile double-shot PBT (non-backlight shine-through)
  • Backlight: RGB with 22+ effects (static white option) / White Backlight version with 14 effects
  • Layout compatibility: Mac and Windows (includes additional keycaps for ESC and Enter)
  • Ergonomics: Three adjustable typing angles

How to use

For wireless use, pair the Keychron K3 Pro with up to three devices via Bluetooth 5.1 and switch between them using the device-selection keys. To program keys or create macros, connect the keyboard with a USB Type-C cable to your computer and use VIA software to remap keys or assign macros; QMK firmware is supported for advanced customization. For competitive or low-latency needs, connect via USB Type-C to enable the 1000 Hz polling rate. To change switches, remove keycaps and hot-swap the low-profile Gateron switches without soldering. Swap the included macOS and Windows keycaps as needed to match your operating system.

Recommendations

Use the wired USB connection when minimal latency is required (gaming or fast input). Ensure you use only compatible low-profile Gateron mechanical switches if you plan to hot-swap, since QMK does not support low-profile optical switches. Keep the VIA software updated for the latest compatibility across macOS, Windows, and Linux.
