  • OAK-1 mounting in an underwater enclosure

Hi,

I'm looking at putting a barebones OAK-1 into an underwater enclosure (rated 400 m) for marine habitat inference and classification. In order do this though I'll need to mount the image sensor at 90 deg to the board as the enclosure isn't wide enough to mount the board as it stands.

So I have a couple of questions:
1) The sensor looks to be securely glued to the board, so before applying too much force can I ask what adhesive was used and from there a suitable solvent can hopefully be found to help separate the sensor?
2) Alternatively can you recommend a suitable replacement sensor from Arducam or elsewhere (fixed focus would be ideal but not essential) that I could then use to attach to the connector and keep the original (unattached sensor) on the board?
Option 2 would be my preference as I could then remount the board as is back into the aluminum housing once the project has finished.

I have seen the OAK-FFC-3P which would be another alternative, but it's dimensions of 60 mm x 40 mm x 22 mm would potentially not fit in the available space in the enclosure.

Can I just say keep up the great work at Luxonis, as I'm just starting to dip my toe in the CNN / disparity depth world and your equipment is a really easy way in. It's very democratizing when the subsea enclosure costs x3 of an OAK-1.

Kind Regards,

    Hello LobsterCam ,
    this looks awesome, looking forward to the results (if you will be able to share them)!
    1) For removing the hot glue it is possible to get some isopropyl alcohol and pour it on the glue and then remove it, or you can heat up the boards a bit on that location and remove the camera module and then clean the glue.
    2) Not actually sure if we have any drop-in replacement for color camera. ArduCam provides fixed-focus color OV9782, but it has different connector.
    Thanks for supporting us and the kind words!
    Kind regards, Erik

      Thanks for the reply, and I'll source some isopropyl alcohol to dissolve the hot glue. It's very much an initial 'how do we fit it all in to the enclosure' stage, but I'll hopefully be able to share results as and when I get them.

      The enclosure that will be used is produced by the team over at Blue Robotics, and it looks like they are OAK-D-Lite backers too:

      Hey John, how did you go with this? We have a spare one of these boards and were thinking of trying to swap the camera to something a bit better for underwater imagery. It would be a super compact module if the camera could be upgraded with a different MIPI camera?

      I haven't looked into the PCB requirements? I assume the board is custom made for the camera, but if I could plug in a IMX577 like this, that would be incredible!

      I've also noticed on the board a number of test points for UART and I2C? Could we connect a sensor to these with a bit of soldering? If we could pass a sensor readings like the OAK-FCC-4P it would be awesome in this form factor? We want to add a barometer sensor to our payload, and sharing the USB-C line would be handy!

        Looks like it could work. The voltage levels are likely the same as on the IMX378 so if the connector is the same one, it should work.

        UART should work as well.

              I contact the Kai Lap Technologies and they provided a datasheet for their IMX577. This notes the mating connector type is an AXE530124 with the following pinout. Is there anywhere I can check the schematic and pinout for the OAK-D-Lite boards to make sure they match?

                  jakaskerl Thanks Jaka, looks like a different pinout. No love unfortunately finding an IMX577 with that pinout. Bummer.
