Installationscheme pixhawk 5x


I’m Mark from the Netherlands. I’m currently designing a baitboat. I have made a simple installationscheme how I think the wiring must be done but I’m not sure and looking for some feedback.
I hope you can help me on my way and maybe you have another idea regarding the version of the pixhaw, the main or secondary gps all tips and trics are welcome!

Thank you already for your help!

Did you get an answer to this? I’m working on a similar setup with a 5x and everything seems to work but I cannot get the motor or steering servo to operate.
