I asked Google's Gemini 2.5 pro for an overview of Keychron keyboards so you don't have to

Keychron has a keyboard for everyone, but it can be hard to know which one to choose.

Here is a breakdown of the key differences between the various Keychron series:

Enthusiast and Customization-Focused Series (Q, V, S)

Q Series

This is Keychron’s premium line, aimed at enthusiasts. Keyboards in this series feature a full CNC machined aluminum case, a double-gasket mounting design for a flexible typing feel, and are fully customizable [33, 35, 36]. Base Q-series models are wired only, but they are fully compatible with QMK/VIA software for key remapping [22, 36].

Q Pro Series

These keyboards build on the Q series by adding Bluetooth wireless connectivity [33, 44].

Q Max Series

The top-tier “Max” versions are an upgrade to the Q Pro series. They add a 2.4GHz wireless connection with a 1000Hz polling rate for low-latency gaming and include additional layers of acoustic foam for an improved typing sound and feel [22, 33, 52].

V Series

This series is positioned as a more budget-friendly entry into the world of custom keyboards. It combines features from the Q and K series, offering QMK/VIA support in an ABS plastic case [22, 45]. Base V-series models are wired-only and typically use a tray mount design [26, 32].

V Max Series

An upgrade to the V series, the V Max models add wireless connectivity (both 2.4GHz and Bluetooth) and feature a gasket mount design for a typing feel closer to the premium Q series [22].

S Series

This is a top-of-the-line low-profile keyboard. It features a full CNC machined aluminum body, is wired-only, and supports QMK/VIA customization [22, 50].

Mainstream and Wireless Series (K)

K Series

This is Keychron’s most popular line, known for its wireless (Bluetooth) connectivity and more affordable price point. These keyboards have a lighter build than the Q series, typically with a plastic case and an optional aluminum frame [33, 35]. Base K-series models are generally not programmable [22]. The series includes both normal and low-profile designs [33].

K Pro Series

An upgraded version of the K series, the K Pro line adds QMK/VIA compatibility, a gasket-mount design, PBT keycaps, and improved sound-absorbing foam [22, 33, 34].

K Max Series

Taking the K Pro series a step further, the K Max versions add a 2.4GHz wireless connection with a 1000Hz polling rate, making them suitable for gaming [22, 33].

Gaming-Focused Series (Lemokey)

Lemokey is Keychron’s sub-brand focused on gaming [65, 67]. These keyboards are designed for performance with features like low-latency wireless connections.

L-Series

These are premium gaming keyboards with full metal bodies, 2.4GHz wireless, and QMK/VIA support [56, 68, 81]. The L3 is a tenkeyless (TKL) keyboard with a volume dial and macro buttons, distinguished from the Keychron Q3 Pro by its 2.4GHz dongle and Cherry-profile keycaps [65]. The L4 is another TKL model but without the extra macro buttons and dial [81].

P-Series

A more budget-friendly gaming line from Lemokey [81]. The P1, for example, is a 75% layout keyboard [54].

X-Series

The X-series consists of entry-level, wired-only gaming keyboards [79].

Budget, Entry-Level, and Specialized Series

HE (Hall Effect) Series

HE is not a standalone series but rather a technology variant within other series, such as the Q1 HE, K2 HE, and Lemokey L5 HE [22, 25, 71]. These keyboards use magnetic switches that allow for unique gaming features like customizable actuation points, rapid trigger functionality, and assigning multiple actions to a single keystroke. They are typically programmed using the brand’s Launcher web app [22, 62].

C Series

This is Keychron’s entry-level, wired-only mechanical keyboard line, ideal for first-time users [22, 45]. The C Pro series is an upgraded version that adds support for QMK/VIA customization [22].

B Series

This is a non-mechanical, scissor-switch series designed to be thin, light, and portable, with a very long battery life. Despite being an entry-level model, it supports keymap changes [22, 25].

Collaboration Series

These are models developed in partnership with other brands, such as the OnePlus Featuring Keyboard 81 Pro [22].

Combo

This refers to product bundles that include a keyboard and a mouse, like the Lemokey X2 with an M55 mouse, rather than a separate keyboard series [73].
