The "Pro" model uses the ZMK firmware. And it's squarely aimed at programmers; the primary way to configure the keyboard is to edit the configuration files and rebuild the firmware- and their documented way of doing this is to fork the configuration files in GitHub and use the included GitHub Actions to actually run the build and generate the firmware blobs. You can do it locally with Docker or Podman, if you don't want to be tethered to GitHub.
