The DJI O3 Air Unit is compatible with both DJI Goggles and the DJI FPV Remote Controller 2, but there are some considerations for installation and control: - Compatibility with DJI Devices: The O3 Air Unit is specifically designed to work with DJI Goggles 2, DJI FPV Goggles V2, and the DJI FPV Remote Controller 2. - Installation in Any Drone: While the O3 Air Unit can be installed in various drones, it requires compatibility with the flight controller. It must be compatible with flight controllers that support Betaflight 4.3.0 or later. - Control with DJI Controller: The O3 Air Unit includes a built-in receiver that allows it to work with the DJI FPV Remote Controller 2. However, if you want to use a non-DJI controller, you may need to install a different receiver, such as an ELRS receiver, and modify the wiring accordingly. In summary, you can install the O3 Air Unit in a drone and control it with both DJI Goggles and the DJI FPV Remote Controller 2, provided the drone's flight controller is compatible. However, using a non-DJI controller may require additional modifications.
