    How should I be wiring the following?:

    GoPro Hero 3+
    Zenmuse H3-3D
    Lightbridge
    Naza M v2

    The Naza v2 PMU only has one extra CAN Bus port, currently I have the Lightbridge plugged into it. Tested and works fine. However, when adding the H3-3D gimbal it also needs to connect to CAN bus, but I have no where to plug it in.

    With this setup, do I need a CAN hub in order to run both Lightbridge and H3-3D?

    Any help appreciated. Thanks!

    What version of the Phantom do you have? The gimbal shouldn't need a canbus connection unless you have a P1 without the upgrade board.

    Thanks for the reply OI.

    It's not on a Phantom, it's for a custom quad.

    I have the Zenmuse H3-3D with GCU v2. The GCU has a G8 port where cable from the gimbal plugs in, an analog A/V output, and CAN Bus port. It came with a very short CAN bus cable.

    The documentation for Lightbridge doesn't seem to cover this configuration. It only covers gimbals with a G7 port that can connect the gimbal to Lightbridge, I assume that is on the higher end gimbals for S800-S1000. Since there is no other way to connect the H3-3D to Lightbridge, I think they both need to be connected to CAN bus.

    Ahh yes ok, on other platforms where you're using the GCU + PMU configuration, you only have one canbus port to start with. A canbus hub is what you need to solve the problem. I would suggest searching for a used one, lots of people around here have an extra one they don't need that came bundled with other hardware they bought (some dealers were putting them in kits that didn't really need them).

    Put up a post in the classifieds section here and I'd bet you'll find someone happy to let their spare go at a decent price.
