I have started to build a mini ROV with two tubes (180x70mm) as pressure housing for electronics, 6 esc & battery.
My plan was to use arduino as controller board for my mini vectored ROV, but now i found the ArduSub Project and this looks perfect.
But the Pixhawk and Raspberry is really big…
So what can i use instead?
APM mini pro or pixhawk lite?
What is the Raspberry for?
Only for ethernet and online video?
What can i take as a small option?
