AULA HERO84 vs Keychron K3 V3: your questions
The AULA HERO84 is better suited for competitive FPS gaming. It has a higher 8000 Hz polling rate compared to the Keychron K3 V3's 1000 Hz, and its Hall effect magnetic switches allow you to fine-tune the actuation point down to 0.01mm for faster trigger responses.
Yes, the Keychron K3 V3 supports Bluetooth 5.2 and can connect with up to three devices wirelessly. The vendor states it is fully compatible with macOS and includes keycaps for Mac layout, making it suitable for use with Apple devices.
Both keyboards are hot-swappable, but with different compatibilities. The AULA HERO84 supports its magnetic Hall effect switches. The Keychron K3 V3's hot-swap sockets are compatible with Keychron Milk POM switches and Gateron low-profile mechanical switches only.
The Keychron K3 V3 is more portable. It weighs 540g and is only 19mm tall, compared to the AULA HERO84 at 910g and 43mm tall. The Keychron's Bluetooth capability also means you don't need to pack a cable to use it with a laptop.
Yes, the AULA HERO84 can be customized using the AULA web driver accessible from Chromium-based browsers. According to the vendor, this allows for key reassignment, macro creation, and control over RGB lighting effects, hue, and brightness.
QMK is open-source firmware that allows for deep, layer-based key remapping, complex macros, and advanced customization. The Keychron K3 V3 supports QMK and VIA, giving users extensive control over their typing experience, which is a significant advantage for programmers and enthusiasts.
Both keyboards feature sound-dampening materials. The AULA HERO84 uses five layers of dampening foam and a steel plate. The Keychron K3 V3 uses a combination of IXPE, EPDM, and latex foam layers, which the vendor claims provides a quiet and responsive typing feel.
Yes, but only with the Keychron K3 V3. It is offered in multiple ISO layouts, including a UK-ISO version. The AULA HERO84 is listed with an ANSI layout only, which uses a smaller Enter key.
Both have per-key RGB, but with different orientations. The AULA HERO84 uses south-facing RGB LEDs, which avoid interference with Cherry-profile keycaps and features a front light bar. The Keychron K3 V3 uses north-facing RGB LEDs with shine-through keycaps for a bright backlight effect.
The AULA HERO84 includes a USB cable, keycap puller, two replacement switches, and a user manual. The Keychron K3 V3's listed contents are not fully detailed in the provided description, but it typically includes a cable and keycap puller for the hot-swap version.
The Keychron K3 V3 could be a better option due to its low-profile design. It has a typing angle of 3° and adjustable feet that provide three angle settings (2.5°, 4.2°, 6.5°), which can help promote a more neutral wrist position compared to a taller keyboard.
