I own 3 Jupiters, 1 Neptune and also had 1 Titan. the Titan controller board died so I replaced it with one of my Jupiter's controller board, and recently the Neptune's controller died and again replaced it with one of my other Jupiter controller boards. All controllers are same.
If you still want pictures let me know and I can take some for you, but they're all going to look exactly the same.
the only difference is that some have 4 ports and others have 6. Not sure if all have the signatures of the dev team printed on the bottom but that was a thing too.
