  • OAK-D Pro PoE with ethernet but powered by external power supply?

Hi,

This page suggests you can power an OAK-D PoE device via USB while still using ethernet as the data connection:

Power the camera via USB-C while still communicating with it through ethernet as in the image below. You need to set static IP on your computer.

The image on the page shows the back of the camera opened up. Is there some way to do this via the M8 connector pins without opening up the camera?

The datasheet alludes to the fact a 5V could be powered through VBUSIN on the M8 connector rather than PoE:
luxonis/depthai-hardwareblob/master/NG9097_OAK-D-Pro-PoE/Datasheet/NG9097_OAK-D-Pro-PoE_Datasheet.pdf

Is it possible to connect via ethernet to the M12 for data and power an Oak-D Pro W Poe via the M8 VBUSIN?

      Hi Jaka,

      That's unfortunate. When you say there are "plans to enable it", can you elaborate? In future devices or firmware for existing devices?

      Also, just to confirm, for an OAK-D Pro PoE, the only way to power the device is 48v via PoE?

        It's a bug really, was supposed to work. So if we can, this will likely be part of future fw. Existing devices ofc, if not possible we can replace your device for one that works.

        You can power it via M8, but then the comms have to also go through the M8.

        Thanks,

            Thank you for the clarification. We would love for this to work. From a power system perspective it's a lot easier for us to provide 5V DC than buck up to 48V just for PoE. So we are very interested in this being an option (power through M8 and comms through M12).

            Any sense for if this may be fixed and when? I'm happy to chat more about it as well.

            Thanks,

              Should work now. Actually it did work before, just not on my machine apparently 😉

                Ha! That's awesome. I didn't have one in hand when I asked but received on yesterday. I just tried it and it works. Thank you!

                Hi all,

                Sorry if I jump in this thread. I'd like to use a OAK-D-Pro PoE.

                If I correctly understand, I can power the device at 5V through the M8 cable, instead than with PoE.

                Two questions:

                • Can I still use the triggers?
                • Is the device still recognized by the SDK as an ethernet device and data sent through the M12 cable?

                Thanks!

                  Yes for both questions. Data should be sent through M12 so depthai handles it as a network device.

                  Thanks,

                      Hi all,

                      One question to add about powering from an external 5V source:

                      • What is the capacitance on the 5V input (or if this is not available, the inrush current when the device is connected to 5V)

                      The context is we need to verify our power supply can successfully power the device (it has an overcurrent protection switch).

                      Thanks!
