# AK·LINK: reconstructing AJAZZ AK820 Pro HID control

> AK·LINK implements Linux control of the AJAZZ AK820 Pro keyboard through its recovered wired HID commands for lighting, per-key RGB and the TFT screen. Its author documents REA-assisted investigation of a separate 2.4 GHz dongle channel, including observed usage pages, checksums and read-only probe responses; native dongle control remains in progress.
