I am converting a 2.5 spec OpenROV into a 2.6 version.
I have the new 2.6 control board and BBB and am using the original versions of the Tenda homeplug adaptors on the ROV and in the Topside Adaptor.
I have soldered new headers onto the 2.6 board for the old style homeplug adaptor.
Currently I just have battery power and tether connected to the DB25 for bench testing.
While I have two green lights (the outside two) on the Topside Adaptor there is no sign of life from the homeplug on the ROV control board or the control board itself (or the BBB).
I am not getting any voltage across the tether wires and I believe the 2.6 board needs a 5v supply from the topside adaptor to turn everything on.
What are the differences between the 2.5 topside controller and the 2.6 version?
