Keychron K3 vs V3: your questions
No. The Keychron K3 uses low-profile optical switches. The manufacturer states that these are not compatible with conventional MX-style mechanical switches. It is only hot-swappable with other low-profile Keychron optical switches.
No. The Keychron V3 is a wired-only keyboard. It connects via the included USB Type-C to Type-A cable and does not have Bluetooth or any other wireless connectivity.
Both keyboards are compatible with macOS and include keycaps for the Mac layout. The K3 vendor page highlights it as suitable for Mac enthusiasts. The V3 includes a system toggle to save separate layouts for macOS and Windows.
The Keychron V3 is available in both knob and non-knob variants. You must select the 'Fully Assembled Knob' or 'Barebone Knob' version at purchase to get the programmable aluminum rotary encoder.
The vendor description for the Keychron K3 does not specify a polling rate. The Keychron V3, however, explicitly lists a 1000 Hz polling rate.
No. The Keychron V3 comes with double-shot PBT keycaps that are not shine-through. It uses south-facing RGB LEDs which are designed to prevent interference with keycaps rather than shine through them.
The Keychron K3 is significantly more portable. It has a smaller 75% layout, a low-profile design, and is wireless with a built-in battery. The V3 is an 80% TKL, wired-only, and weighs 1120 grams, making it a desk-bound keyboard.
The vendor description for the K3 does not mention any software for key remapping or macro programming. For extensive reprogramming, the Keychron V3 with its QMK and VIA support is the designed choice.
The fully assembled Keychron V3 comes with pre-lubed Keychron K Pro switches. Options include Red (linear), Brown (tactile), and Blue (clicky). The barebone version does not include switches.
Yes, the Keychron K3 is available in both RGB and white backlight versions. The vendor description mentions it has 18 types of RGB backlight settings.
The V3 focuses on custom keyboard foundations with a steel plate, screw-in stabilizers, and sound dampening foam in a plastic case. The K3 uses an aluminum top case and plastic plate for a slim profile, prioritizing lightness over a heavy, mod-focused construction.
Only the wireless Keychron K3 has a battery. It is equipped with a 1550mAh rechargeable battery. The manufacturer states it can last up to 34 hours on the lowest backlight setting. The wired V3 does not have a battery.
