Features

Compact 80% Tenkeyless Layout

The C3 Pro features an 80% tenkeyless layout that retains function keys, navigation controls and directional arrows while removing the numeric keypad. This design provides additional desktop space for mouse movement without sacrificing essential keyboard functions.

Pre-Lubed Keychron Red Mechanical Switches

Equipped with Keychron mechanical Red switches, the keyboard delivers smooth linear keystrokes without a pronounced tactile bump. Factory pre-lubrication helps reduce friction and provides a consistent typing feel for gaming, writing and everyday computer use.

Responsive 1,000Hz Polling Rate

The C3 Pro features a 1,000Hz polling rate, allowing the keyboard to report input to the connected computer every millisecond. This supports responsive keyboard operation during fast-paced gaming, typing and other interactive applications.

QMK/VIA Programmable Functionality

Open-source QMK firmware and VIA configuration support allow users to customize keyboard layouts, assign alternative key functions and create macros. This provides flexible control for gaming shortcuts, productivity applications and personal workflows.

Gasket-Mounted Keyboard Construction

The gasket-mounted design provides a more flexible typing structure compared with conventional rigid mounting arrangements. Combined with internal acoustic foam, it helps reduce vibration and unwanted resonance during mechanical keyboard operation.

Acoustic Sound-Absorbing Foam

Integrated sound-absorbing foam helps minimise hollow keyboard sounds and internal resonance. This contributes to a more refined acoustic profile and comfortable mechanical typing experience.

Red LED Backlighting

North-facing red LEDs illuminate the keyboard with adjustable lighting effects. The backlighting enhances key visibility in dim environments and complements the keyboard's black and red appearance.

Double-Shot ABS Keycaps

The keyboard features OEM-profile double-shot ABS keycaps with shine-through legends. Their dual-layer construction helps maintain clear key markings while allowing the red LED lighting to illuminate the characters.

High-Performance ARM Processor

An ARM Cortex-M4 STM32F402RC 32-bit microcontroller with 256KB flash memory supports responsive keyboard processing and advanced QMK/VIA functionality. This hardware provides the foundation for consistent input performance and programmable controls.

Full N-Key Rollover

N-key rollover technology enables multiple simultaneous key presses to register accurately. This functionality supports gaming combinations, complex shortcuts and fast typing without missed key inputs.

Comfortable Adjustable Typing Angles

The keyboard offers three adjustable typing positions of approximately 4, 6 and 8.7 degrees. Combined with curved OEM-profile keycaps, these settings allow users to select a suitable typing position for their workspace.

Durable ABS and Steel Construction

The C3 Pro combines an ABS plastic housing with a steel mounting plate. This construction provides a stable foundation for mechanical key operation while maintaining a practical desktop-friendly design.

Reliable USB-C Wired Connectivity

USB Type-C connectivity provides a stable wired connection to compatible computers. The supplied USB Type-A to Type-C cable supports straightforward installation without requiring wireless pairing or battery charging.

Windows and macOS Compatibility

The C3 Pro supports both Windows and macOS environments, with additional keycaps included for platform-specific layouts. Its programmable functionality allows users to customize keyboard shortcuts for their preferred operating system.

Suitable for Gaming and Productivity

The combination of Red linear switches, responsive polling, programmable keys and compact construction makes the C3 Pro suitable for gaming, office applications, programming and everyday typing.

Care and Maintenance

Clean the keyboard using a soft, dry cloth or suitable keyboard cleaning brush. Disconnect the USB cable before cleaning. Avoid excessive moisture and abrasive products. The C3P-A1 uses fixed mechanical switches and is not designed for hot-swappable switch replacement.
