  Unfortunately, I'm not aware of any such documentation.

  @Chad-Sweet Thanks for your reply. This is the exact answer I was looking for. The flight core is perfect but here at our company we need to use different Pixhawk board for some specific application.

  This is a known bug that was fixed in voxl-vision-px4 v0.8.8 which is currently on the development repo, scheduled to be merged into the stable repo in a week or so. The bug is not caused by PX4, it was due the the handling of the specific mavlink packet containing console data. It should behave normally when not using the PX4 console.

  @PawelJ There isn't an exact way to do that, if you want you could edit your initial question and add a [SOLVED] section at the top and describe the solution.

  Hi Nikhil, Sorry for our delayed response on this. I just recently joined our forum to help out with more HW centric question. As Chad mentioned, this does require HW mods if you do not want the SW driver timestamp method (which would be our recommendation/preference). The Lepton signal VSYNC (on GPIO3 most likely is what you are referring to) is running at the VIO voltage of 2.8V to 3.1V per Lepton specs. Our camera sensors are MIPI based, and as such all of those I/Os are at 1.8V, so a level translator would be required which makes connecting these a bit tricky, especially if you need bi-directional support with another sync controller/snoop device. This would need to be something done on a custom interface between the Lepton and the stereo sensors. We do not have such module but would be happy to give further guidance if you need it. Thanks! Vinny

  Your understanding is correct, ModalAI's supported configurations are a result of Qualcomm limitations

  Thank you Travis! I made another cable today and it was recognized as usb3 device. I guess the quality of the first cable was too bad in the first place or I did a bad job switching the channels. However, until now I did not manage to create a robust connection. The driver behaves wierd and especially in the docker container I was not able to use the bandwidth. This is probably usb-driver or device related so I will try to play with the kernel parameters. Anyhow, in theory it now works, so thanks a lot! (Also for the writeup, probably others can benefit from that.)

  Nevermind, apparently I looked in the wrong places: https://dev.px4.io/master/en/ros/external_position_estimation.html has the answer: EKF2_HGT_MODE must be set to vision to use the voxl odometry instead of the barometer. Closing this.

  Sorry, we don't currently support RealSense. The VOXL flight deck comes preconfigured with similar functionality
