X8 Pixhawk Wiring Schematic Diagram

Posted by John Kleiber on March 5, 2015 at 11:45am

Hello all!

I am in the process of completely re configuring my 3drobotics Y6 with APM to a Carbon Fiber X8 with Pixhawk. Originally when I built my Y6 I neglected to properly document my build as to wiring etc, however I am drawing out my X8 wiring this time in its entirety.

Here is my wiring so far. Blue dashed boxes indicate that I still need to work on radio, fpv and motor wiring illustrations.

My main question at this point is,  Am I on the right track regarding the Pixhawk connectivity to the ESC's and PDB wiring for a X8 setup?

    Hi,

    Do you know why pixhawk doesn't really work well with Walkera G - 3S Gimbal ?

    I fixed the GPS wiring and added (2) 12v spare leads from the PDB "12v Reserved for future use" and (2) 5v leads from the ESC/BEC "5v Reserved for future use".

    Your suggestion will come in handy because currently I am running my fpv on a separate battery.

    If you see something wrong on my wiring, let me know.

    My original image has been updated to reflect your suggestions.

    Thanks

    Hi,

    I think your wiring for the second GPS should go to serial4/5 with a 6 pin cable, not on the I2C bus with a 4 pin cable (that is reserved for compass, not GPS).

    Also I would advise you to add a couple of extra POS/NEG wires, soldered on the PDB, so that you could use them later on to feed some BECs (when you'll need them, or to have a backup power of pixhawk via the servo rail).

    Another tip when you're soldering and installing your ESCs, label every cable so that you can identify : motor number and which three motor wires connect to which three ESC wires (rotation direction).

    Good luck with your build.

      Your right, my secondary GPS wiring was not correct, I must of copied/pasted and forgot to change the wiring. I verified your suggestion here GPS Wiring

      Adding spare +/- wires to PDB, Good idea, OK no problem

      I have a label gun and fine tip paint pens so labeling is covered for my motor & esc connections.

      By the way, these Paint Pens work great for nice neat labeling on wires or dark surfaces. Very durable.

      Thanks for your help.

      John
