Keychron V1 vs V275% vs 65% Layout Custom Keyboard Choice

The core difference is the layout size. The V1 is a 75% keyboard, which includes a function row and a column of navigation keys. The V2 is a 65% keyboard, which removes the function row and some nav keys for a more compact footprint, while keeping the arrow keys.

Yes, both keyboards feature hot-swappable PCBs. This allows you to change the mechanical switches without any soldering. Both support 3-pin and 5-pin MX-style switches.

Yes, both keyboards fully support QMK and VIA firmware. This means you can remap any key, create complex macros, and adjust lighting layers using the open-source VIA configurator or Keychron's own Launcher web app.

Both the V1 and V2 are available in versions with and without a programmable aluminum knob. You can choose a 'Knob' or standard version when purchasing either the fully assembled or barebone kit.

The Keychron V1 is generally better for programming. Its 75% layout provides direct access to the function row (F1-F12) often used for IDE shortcuts and debugging, as well as dedicated navigation keys like Home, End, PgUp, and PgDn without needing a modifier layer.

The Keychron V2 is capable for gaming, featuring a 1000 Hz polling rate. However, the V1 may have an edge for some gamers because it offers a higher 8000 Hz polling rate option and has dedicated keys for macros or in-game commands on its function row.

According to Keychron, both the V1 and V2 fully assembled versions come with double-shot PBT keycaps in the OSA profile. These are non-shine-through keycaps that include extra keys for both macOS and Windows layouts.

The Keychron V2 is more portable. It is a 65% size keyboard, making it significantly narrower (123mm vs 148mm) and lighter (855g vs 995g) than the 75% V1. This makes it easier to carry and fit on small desks.

Yes, both keyboards feature south-facing RGB LED backlighting. South-facing LEDs are designed to prevent interference with Cherry-profile or OEM-profile aftermarket keycaps and provide better lighting from the typist's perspective.

The Keychron V1 offers gasket mount, tray mount, and plate mount styles according to its specifications. The Keychron V2 uses tray mount and plate mount designs. Gasket mount, available on the V1, can offer a more flexible typing feel.

Both keyboards come equipped with screw-in PCB stabilizers. According to Keychron's product descriptions, these screw-in stabilizers are designed for increased stability, less rattle, and are easier to upgrade or modify compared to clip-in stabilizers.
