Here are Eagle schematic and board files as well as BOM for the ROV power board.
I moved all the high voltage/current stuff to a separate PCB and separated the control connections by using optocouplers.
That should help avoiding the electrical noise from the power MOSFETs switching at 20 kHz for the thruster motors.
|1||TE Micro-MaTch 12 pos female||6804978||Or just solder wires directly to the board|
|1||TE Micro-MaTch 12 pos male||6804993|
|1||12 lead ribbon cable||2899852||This is actually 14 leads. Peel off two or use separate wires.|

|6||SMD capacitor||100 µF||7472871|
|6||Ceramic bypass cap. 0805||0.1 µF||6480979||Or any other 0.1 µF 0805 ceramic cap.|
The past few days, the media have been having a field day with the "now you can 3D print you own gun" story. (Here on BBC for example).
Do yourself a favour and read this comment on Hackaday before you join the choir…
