The Q1 HE incorporates the innovative Gateron Double-Rail Magnetic Purple magnetic switches, which eliminate the physical contacts of traditional mechanical switches in favor of magnetic detection. The dual-rail structure ensures absolute stability of the stem, while the specially designed TMR (Tunneling Magnetoresistance) sensors detect changes in the magnetic field with exceptional accuracy. This technology allows for sensitivity of 0.1 mm and durability for millions of keystrokes due to reduced friction. The sensors provide high-resolution detection of distance and magnetic field (up to 100 mV/V/Oe), eliminating latency and offering a linear, smooth feel without the effect of debounce delay.

The circuit of the Q1 HE is powered by a powerful microcontroller (MCU) with ARM architecture and 256K Flash memory, which manages high-speed signal processing. In 2.4 GHz mode via the included receiver, as well as in wired USB Type-C connection, the keyboard achieves a polling rate of 1000 Hz, ensuring zero latency for e-sports level gaming performance. At the same time, it features Bluetooth 5.2 for wireless connection with up to 3 devices simultaneously (PC, tablet, smartphone), offering flexibility for multitasking scenarios. Switching between modes is done instantly via a physical switch on the back.

As an open-source platform, the Q1 HE fully supports QMK firmware, offering unlimited programming possibilities. Through the online Keychron Launcher application, the user can access all the settings of the magnetic switches without installing any software (bloatware). The interface allows precise adjustment of the actuation point, creation of complex macros, key remapping, and management of RGB lighting. The settings are stored directly in the keyboard’s built-in memory, making it independent of the operating system (Windows, macOS, Linux).
