    It's so tempting to buy a Phantom 1.1.1. They're on sale for $399 new. I've checked and the NAZA has a PMU.
    I'd like to use the cheap Goodluckbuy gimbal and add a mini-iOSD without adding an upgrade board.
    Probably have to install can bus before mini-iOSD - and add FPV later.
    What is the easiest way to set up this config?

    It depends on what you mean when you say the "NAZA has a PMU."

    All Phantoms come with voltage regulator circuitry, it's necessary to convert the 11.1v battery down to 5v to power the NAZA and accessories. That is, technically, a "power management unit." But NO Phantom comes from the factory with a separate PMU-V2 module, which has the CANBus transceiver and I2C converter necessary to get CAN support needed for the iOSD mini. For CAN, you need either a PMU V2 or a Phantom upgrade board.

    The answer to your question depends on whether the Phantom you're looking at has been modified by a 3rd party to include a PMU V2 (and I know of no reason why any retailer would do that without adding on the ~$65 cost of the PMU V2 unit).

    If you're using a 3rd party gimbal and you don't need flight data directly from the NAZA, you don't need CANBus. You can get some of the same OSD info as from the iOSD-mini with such a standalone unit, but not all of it and it won't be synced with the flight controller.

    ElGuano, Thanks for the clarifying the distinction between onboard PMU and the PMU V2.

    Yes, you can install the upgrade board simply for CANBus and iOSD mini support, and run a 3rd party gimbal (that's actually what I do). The Zenmuse is the only gimbal that NEEDS CanBUS, everything else has its own dedicated controller board that doesn't communicate with the NAZA at all.

    I too will be adding an iOSD soon.

    I just completed my FPV setup, so now all that's left is adding in some type of monitor that tells me how high/far away I am and where to get back to the home spot. I'm debating whether I want to go through all of the trouble with the upgrade board and stuff.
