Keychron K3 V3 vs Q3Low-Profile Wireless vs Full-Size TKL

The Keychron K3 V3 is designed for wireless use with Bluetooth 5.2, connecting to up to 3 devices. The Keychron Q3 does not support wireless connectivity at all, it is wired-only via USB-C. For a cable-free setup, the K3 V3 is the only option.

No, the K3 V3 is only compatible with low-profile mechanical switches such as Keychron Milk POM or Gateron low-profile switches. Standard MX switches are taller and will not fit the low-profile PCB or keycaps.

Yes, the Keychron Q3 includes a programmable aluminum rotary encoder knob. You can customize it via VIA software to control volume, zoom, brush size, or backlight brightness among other functions.

The Keychron K3 V3 uses an ABS and aluminum frame, while the Keychron Q3 features a full CNC machined 6063 aluminum body. The Q3's all-metal construction provides a more solid and premium feel but adds significant weight.

The Keychron Q3 is easier to mod due to its hot-swappable PCB that supports 3 and 5 pin MX switches, screw-in stabilizers, and a gasket mount that can be tuned. The K3 V3 is hot-swappable but only with low-profile switches and has a more compact, less open structure.

Yes, both the Keychron K3 V3 and Keychron Q3 support QMK firmware and VIA software for full key remapping and macro creation. The K3 V3 uses the Keychron Launcher web app, while the Q3 can be configured with the desktop VIA software or Launcher.

The Keychron Q3 uses screw-in PCB stabilizers for increased stability and less wobble. The K3 V3 features redesigned plate-mount stabilizers that improve reliability on big keys but are not as rigid as screw-in ones.

The Keychron K3 V3 weighs only 540 grams, making it highly portable. The Keychron Q3 weighs approximately 2000 grams, more than three times heavier, due to its full aluminum construction.

Yes, both the K3 V3 and Q3 include a system toggle switch and come with extra keycaps for macOS and Windows. They are designed to work seamlessly with both operating systems.

Yes, the Q3 features a double-gasket design with silicone pads between the top and bottom cases to reduce acoustic resonance. It also includes sound dampening foam in the case to minimize echo and ping.

Both keyboards have RGB backlighting. The Keychron K3 V3 uses north-facing RGB LEDs, while the Keychron Q3 uses south-facing RGB LEDs to reduce interference with aftermarket keycap profiles like Cherry.

Yes, the Keychron Q3 is available in barebones versions (Carbon Black, Silver Grey, Navy Blue) that come without switches and keycaps, allowing you to build your own setup. The K3 V3 does not offer a barebones option.
