Keychron Q9 vs NIUNIU @40: your questions
The NIUNIU @40 is designed for wireless use. Its product listing specifies available configurations with Bluetooth and 2.4 GHz wireless connectivity, and includes batteries for those modes. The Keychron Q9 is a wired-only keyboard.
No, you cannot use standard Cherry MX keycaps on the NIUNIU @40. It is a low-profile keyboard, which requires specific low-profile switches and matching keycap mounts that are incompatible with standard MX stem keycaps.
Yes, the Keychron Q9 supports both Mac and Windows systems. The vendor description states it includes a system toggle and an additional set of keycaps for both operating systems, allowing you to save different layouts for each.
The Keychron Q9 has a typing angle of 5 degrees, as listed in its specifications. This is a fixed angle determined by its case design.
Yes, the NIUNIU @40 features a hot-swappable PCB according to its vendor description. This allows you to change switches without soldering, though it is limited to compatible low-profile switch types.
Only the Keychron Q9 has RGB lighting. It features south-facing RGB LEDs, which the manufacturer states prevent interference with Cherry-profile keycaps. The NIUNIU @40 does not have any backlighting.
A split spacebar divides the traditional space key into two or three separate keys. The Keychron Q9 Plus version offers this design, allowing you to remap the additional keys to functions like Backspace or Delete. The NIUNIU @40's layout options are standard or ortholinear.
Yes. While the Keychron Q9 supports the open-source QMK firmware, it also supports VIA and the Keychron Launcher web app. The vendor states you can easily remap keys and customize the knob through these graphical interfaces without writing code.
The Keychron Q9 uses a steel plate. The NIUNIU @40 kit includes an FR4 plate, as per its 'What's inside the box' list, which is a fiberglass composite known for a specific sound signature.
The NIUNIU @40 is more portable. Its low-profile design is slimmer, it is wireless so it doesn't require a cable, and it is likely lighter than the 1050-gram all-metal Keychron Q9. The @40's vendor also highlights portability as a focus.
The Keychron Q9 is available as a fully assembled version with Gateron G Pro or Keychron K Pro switches and OSA PBT keycaps, or as a barebones kit without them. The NIUNIU @40 is sold as a kit that does not include switches or keycaps, only Kailh low-profile stabilizers.
The NIUNIU @40 supports VIAL for programming, as stated in its product metadata. VIAL is a graphical configuration tool similar to VIA, allowing for key remapping and macro creation without compiling firmware.
