    I'm looking for a bit of instant wisdom and knowledge.

    I have recently purchased the HDMI output module for my Phantom 4 Pro (to allow the use of clean video in DJI Goggles) and I am puzzled by one of the ports on it. I can spot the HDMI port (obviously) and also a full-size USB and micro USB, but it is the curious 4-pin port between the two USBs that I can't place. Neither do I recognise its symbol. In the DJI Phantom 4 Pro User Guide (screen capture attached) the drawing of the output module installed on the Plus model looks different, with the ports in a different layout (including the HDMI port itself).

    Although ordered from DJI as a Phantom 4 add-on, the item received was labelled 'Phantom 3'. But I think that is correct, as I believe the HDMI module hasn't changed since the Phantom 3. YouTube videos of fitting the HDMI module to a Phantom 4 or 4 Pro all show its packaging as being Phantom 3.

    Can anyone identify the mystery port please?

    Tony.

    It has no documented use. Perhaps DJI included it for a feature they had in mind for the future.

    Yes, it's the correct item. There is only one HDMI output module.

    It's a CAN bus port.

    Thanks AirMan. I am familiar with CAN bus on motor vehicles, but was unaware of its inclusion on a drone.
