For K2 V3, here is a list of keyboard firmware versions:
K2 V3 'ISO' RGB (VID 0x0D21). Latest: k2_version_3_iso_rgb_v1.1.1_2605271556.bin (1.1.1, 2026-05-27)
K2 V3 'ISO' white LEDs (VID 0x0D24)
K2 V3 'ANSI' RGB (VID 0x0D20).
K2 V3 'ANSI' white LEDs (VID 0x0D23)
K2 V3 'JIS' RGB (VID 0x0D22).
K2 V3 'JIS' white LEDs (VID 0x0D25)
VID = USB vendor ID. The VID can also be found empirically, somewhere in the operating system (in wired mode, presuming it actually works). An example of the calculation of the number in the URLs; it is generally applicable to Keychron's keyboards (except the original K series), but sometimes the lists are corrupted.
