Keychron Q1 HE QMK Wireless Custom Keyboard

The Keychron Q1 HE sits at a genuinely unusual intersection of features. It is, according to Keychron Australia, their first 75% wireless keyboard to combine Hall Effect magnetic switches with QMK open-source firmware support — a combination that until recently existed only in wired custom keyboards or gaming boards with proprietary software. At AUD $349.00, it positions itself above mainstream gaming keyboards but below the upper tier of boutique custom keyboards, and the feature set it brings to that price point deserves careful examination.

Who Is This Keyboard For?

The Q1 HE makes most sense for a specific kind of buyer: someone who wants genuine custom keyboard build quality and QMK programmability, but also needs reliable wireless connectivity for a cleaner desk or multi-device workflow. It also appeals strongly to gamers who want rapid trigger and adjustable actuation — features that require Hall Effect switch technology — but who prefer the refined aesthetics and construction of a custom board over a purpose-built gaming keyboard.

It is less suited to buyers who primarily want budget value, who need a full-size or tenkeyless layout, or who require compatibility with the broader universe of third-party mechanical switches.

What Makes Hall Effect Switches Different

Understanding the Q1 HE requires a brief primer on its switch technology. Traditional mechanical switches use a physical contact point — a metal leaf or click mechanism — to register a keypress at a fixed actuation point. Hall Effect switches instead use a magnet inside the switch stem and a magnetic sensor (in this case TMR — Tunneling Magnetoresistance technology, with magnetic field sensitivity up to 100 mV/V/Oe) on the PCB to detect position continuously, with no physical contact involved.

This enables two significant capabilities that mechanical switches cannot replicate:

Adjustable actuation points. The depth at which a keypress registers can be set by the user per-key. The AU product page lists a range of 0.1–4.0 mm; the global Keychron page lists 0.2–3.8 mm. The two specifications conflict, and Letherium has not been able to independently verify which is accurate for current production units — buyers should check Keychron's current product page before purchasing if the precise range matters to them.

Rapid trigger. Rather than requiring the key to fully reset before registering another press, rapid trigger allows re-actuation as soon as the key moves upward by the sensitivity threshold. The Q1 HE lists a sensitivity of 0.1 mm, meaning the switch can re-register after just a tenth of a millimetre of upward travel. This is a meaningful advantage in competitive gaming for keys used in rapid alternating inputs.

Dynamic keystrokes. The Q1 HE supports what Keychron describes as 4-in-1 action keys, allowing up to four different actions to be assigned to a single key based on press depth. This is a QMK-level feature unique to analog Hall Effect input.

Build and Construction

The Q1 HE carries the physical profile Keychron has established in the Q series. The body is 6063 aluminium, the plate is also aluminium, and the mounting system is a double-gasket design — silicone pads between the top and bottom cases, plus an acoustic foam pad on the bottom case. Screw-in PCB stabilisers are used for the larger keys.

Dimensions are 327.5 mm × 145 mm, with a front height (without keycaps) of 22.6 mm, a back height of 35.8 mm, a typing angle of 5.2°, and adjustable feet adding 2.4 mm when deployed. Fully assembled weight is 1,735 g ± 10 g — this is a heavy keyboard, and that is worth noting plainly. It will not move around on a desk, but it is not something you would carry in a bag without deliberate packing.

The keycaps are OSA (OEM Spherical Angled) double-shot PBT. They are not shine-through. Both Mac and Windows keycap sets are included in the box, along with a 1.8 m Type-C cable and a Type-A to Type-C adapter.

Colour options are Carbon Black and Shell White.

Wireless Connectivity

The Q1 HE supports three connection modes: 2.4 GHz wireless (via USB dongle), Bluetooth, and wired Type-C. Bluetooth multi-device pairing supports up to three devices simultaneously, and there is a physical toggle on the keyboard to switch between Mac/iOS and Windows/Android keymapping.

Polling rate is 1,000 Hz over wired and 2.4 GHz connections, and 90 Hz over Bluetooth. Competitive gamers who prioritise lowest latency should use the 2.4 GHz connection for gaming specifically; the Bluetooth polling rate is suitable for general productivity use but is not competitive-grade.

The battery is a 4,000 mAh Li-polymer cell. The official manual states a charge time of around five hours via the USB Type-C port. The global Keychron page lists wireless working time at up to 100 hours with the backlight off. Wireless range is listed as within 10 metres in open space.

There is a minor specification conflict on Bluetooth version: the AU page lists Bluetooth 5.1, while the global page lists Bluetooth 5.2. The verification notes suggest the global page likely reflects a newer production revision. Buyers who need to confirm the exact Bluetooth version should check directly with Keychron Australia or the current product listing.

Software and Programmability

The Q1 HE runs QMK open-source firmware. Configuration is done through the Keychron Launcher, a browser-based web app that requires Chrome, Opera, or Edge, and a wired connection for any programming changes. Two layouts can be saved on-board — one per OS. The system toggle switches between the saved Mac and Windows profiles automatically.

The MCU is an ARM Cortex-M4 32-bit STM32F402 with 256 KB flash. The AU page lists the suffix as STM32F402RC; the global page omits the suffix. This is a minor discrepancy that likely reflects a documentation difference rather than a meaningful hardware change.

QMK support is a significant differentiator at this price point for buyers interested in deep customisation — key remapping, layers, macros, per-key actuation adjustment, and rapid trigger configuration are all accessible through the firmware.

Switch Hot-Swap and Compatibility

The Q1 HE is hot-swappable, but with a meaningful restriction: it is compatible only with Gateron double-rail magnetic switches. Standard mechanical switches will not work in this PCB. The double-rail design is a physical and electrical requirement of the Hall Effect sensor system, not a marketing limitation.

The default switch included is the Gateron Double-Rail Magnetic Nebula Switch. Replacement and alternative Gateron double-rail magnetic switches are sold through the Keychron website. Buyers who want the flexibility to swap to any third-party switch should be aware that this keyboard does not provide that.

Key Specifications at a Glance

Buying Considerations

Buy if: You want the combination of a properly built custom keyboard chassis, QMK firmware, and Hall Effect switch technology in a wireless package. This is a niche that essentially did not exist before boards like the Q1 HE, and the specification set is coherent and well-thought-through for its intended audience.

Consider alternatives if: You want full switch compatibility with third-party mechanical switches, need a lighter portable keyboard, require maximum RGB legibility through shine-through keycaps, or are buying primarily for productivity rather than gaming and find the Hall Effect feature set irrelevant to your use case.

Knob variant note: A Fully Assembled Knob variant of the Q1 HE exists, adding a rotary encoder knob. Buyers who want that feature should confirm availability of that specific variant from their retailer.

WIRED highlighted the Q1 HE's Hall Effect switches and their key-press customisation capabilities. PCMag Australia has also included the Q1 HE in its wireless keyboard coverage. Letherium has not independently tested this product.

Verdict

The Keychron Q1 HE is a technically specific product that does something most keyboards in its price range do not: it combines Hall Effect magnetic switch technology, QMK open-source firmware, and triple wireless connectivity in a premium aluminium 75% chassis. For the buyer who specifically wants those three things together, the Q1 HE is currently one of very few options that deliver them.

The trade-offs are real and worth understanding before purchase. Switch compatibility is locked to the Gateron double-rail magnetic ecosystem. The keyboard is heavy. Bluetooth gaming use is limited by the 90 Hz polling rate. And the specification discrepancies between the AU and global pages are a minor but genuine irritation that buyers comparing specifications across sources should be aware of.

At AUD $349.00, it is positioned as a considered purchase rather than an impulse buy. Buyers who have identified Hall Effect wireless QMK functionality as a genuine need will find few better-specified options. Buyers who are still deciding whether those features are relevant to them should work through the feature set carefully — the Q1 HE rewards buyers who understand what they are paying for.
