I have been doing a lot of research and starting my build based off of ROV2. So far I have a RPi2, Pixhawk and some miscellaneous motors and ESCs I have been testing with before I buy more parts. I would like to homebrew as much as I can and learn about everything in the process.
Anyways, regarding the Fathom-X interface. I will be powering my ROV with an onboard battery and was planning on just running Cat5 through hallow-braid poly for my tether. I am trying to figure out what the real purpose of the interface is. Can I not just run the Cat5 based tether from the ROV straight to my laptop (or wifi AP)?
Any help would be appreciated as I decide what my next round of purchases are going to be.
