The Keychron K9 Pro is a 60% layout low-profile mechanical keyboard with QMK/VIA support.
This is the second example, following K13, of a “Pro” series in which there is no so-called “unbranded model,” and its compact looks give the impression that it will be popular for portable use.
The keyswitches are newly developed Gateron Low-Profile 2.0 red- and brown-axis, featuring a 3.2 mmn deep stroke that approaches that of a regular mechanical keyboard despite its low profile.
Of course, since it is hot-swappable, it can be converted to the highly reputed Gateron x NuPhy “Wisteria” and “Daisy”.
The stabilizer is also newly designed, and together with the double-shot PBT keycap, will produce a solid keystroke feel.
The typing angle has three settings (3.4º, 5º , 8º), and the low-profile design allows comfortable use without a palm rest.
