Keychron Q1 vs Q275% vs 65% Layout Comparison for Custom Builds

The primary difference is the layout size. The Q1 is a 75% keyboard, retaining the function row, arrow keys, and a column of navigation keys. The Q2 is a 65% keyboard, which removes the function row and some nav keys for a more compact footprint, requiring the use of a function layer to access those keys.

Yes, both the Keychron Q1 and Q2 feature hot-swappable PCBs. This allows you to install or change mechanical switches without any soldering. Their PCBs support both 3-pin and 5-pin MX-style switches.

Yes, both keyboards are fully programmable using the open-source QMK firmware and the VIA configuration software. This allows for extensive key remapping, macro creation, and layer configuration directly through a user-friendly interface.

Both keyboards are available in versions with and without a programmable rotary encoder (knob). You can purchase a fully assembled or barebones kit with a knob, or opt for a version without one, depending on your preference and workflow needs.

According to vendor descriptions, the fully assembled Q1 ISO version comes with OSA profile ABS backlight shine-through keycaps. The fully assembled Q2 comes with double-shot PBT keycaps in the OSA profile, which are generally more wear-resistant than ABS.

Yes, both the Q1 and Q2 are designed with Mac compatibility in mind. They include keycaps for both macOS and Windows layouts, and the vendor description for the Q1 specifically mentions it comes with a Mac multimedia key layout. A system toggle allows you to switch between macOS and Windows key mappings.

Both keyboards utilize a gasket mount design. Keychron's implementation is a double-gasket design, which includes silicone pads between the top and bottom cases in addition to gaskets on the plate, aimed at reducing metal resonance and improving typing sound.

Both keyboards feature a full CNC-machined aluminum case, which provides a solid, premium feel. They also include screw-in PCB stabilizers for larger keys, a steel plate (with additional plate options for the Q1), and sound-dampening foam inside the case.

Yes, both the Keychron Q1 and Q2 have south-facing RGB LEDs. This orientation helps prevent interference with Cherry-profile keycaps and is designed to better illuminate the keyboard from the typist's perspective.

The Keychron Q2 is more portable. It has a smaller 65% footprint with a width of 121mm compared to the Q1's 145mm. The Q2 is also lighter, weighing 1645g versus the Q1's 1825g, making it easier to transport.

Yes, both keyboards support ISO layouts. The Q1's vendor description specifically highlights a collection with UK, German, Nordic, Swiss, French, and Spanish ISO layouts. The Q2 also lists support for multiple ISO standards, including DE, Nordic, UK, FR, ES, and SW.

Both the Keychron Q1 and Q2 have a polling rate of 1000 Hz, as listed in their specifications. This provides a 1ms report rate for responsive input in gaming and general use.
