@mbahrami Modal AI ESC&2203.5 -- I don't see any reason why this wouldn't work. Battery voltage selection depends on how fast you need to spin the given prop of choice to generate sufficient lift/performance you need in your platform. If you spin the motor at one speed with 3S and that generates the performance you need then go with that. If you move to 4S and in doing so get the performance you want in terms of speed, endurance etc then go with 4S. Really depends on what your goals are. You can pick up a variety of battery pack configurations from any drone/FPV store and try those out -- just make sure you match your connector or get an adapter. Here are some posts on USB Cameras. I have tried this with some -- it works. https://docs.modalai.com/uvc-streaming/ https://docs.modalai.com/voxl-streamer/ For something like the Zed2 you probably need some custom drivers on the VOXL to work properly. Re: other color cameras -- defer to the ModalAI team on those. Hope this helps, Steve

Hi, i think your issue is the board size, it's counting the number of inside corners not the number of squares so it should be 6x8 not 7x9

It should be possible to plug in the hires cam to j4 and have frames appear, but vio server and the camera calibrator are not set up to handle the non-fisheye color images, I'd strongly recommend getting a new tracking camera from here

@serge There is more information here: https://docs.modalai.com/usb-to-ethernet-with-voxl/

Hi @Matt-Turi ! You right. I hardcoded tflite server channel, so I forgot to change it when setting callback function. Now, my code works fine. Thank you very much for your enthusiastic help!

Hi @jrestifo , Super late on this response. In general yes a kernel rebuild is needed. There's some gotchas so if you are proceeding down this path let us know.

This is for the STM32 based FlightCore.... not SLPI which I think you're super aware of but making sure!

Is that version of GPS module supported in the version of PX4 you are using? Is it wired properly to your flight controller as well?

Thank you for your reply. Its working now

@RichieRich Hi rich thanks for response. After reboot everything went normal, In this flight we the aid mask was default 1.

@Chad-Sweet That is what I was thinking. I'll check in with the boss and see what he wants to do. Thanks!

@Zeev-Mindali Checkout your options here: https://www.modalai.com/pages/rma

Yes, this "can" work, but it is not ideal due to the many unknown variables on someone's host PC. Hence it is not a default option, and we would not recommend it. Issues can range from USB VBUS being out of spec (as it is, it is allowed +/- 10% which puts it in on the edge of our needs), and most "correctly designed" PCs will not provide more than 100mA unless a device is enumerated that asks for more. I'm not sure if all version of PX4 do that correctly. 100mA is insufficient for most use cases. In a strictly "QGC config" mode, I can see this work, but it is not something we plan on supporting on this version board due to those risks above. This also opens the door for someone to leave that power feed in-place while then later connecting the power module which will create a serious power rail shorting problem between the module and the PC. However, we do have a design already figured out that can take USB power for QGC/Config type of applications, and it validates the VBUS through a smart fuse/mux before using it. This will allows us to globally claim support, and if someone's system is not correct or out of range, we protect the HW. Stay tuned!

@張為超 voxl-emulator is a docker image that emulates the environment https://docs.modalai.com/voxl-emulator/.

Yes, that should be fine VOXL Micro SD Card SDXC Version 3.0 up to 2TB PX4 Supported SD Cards SDHC version 2 up to 32GB Datasheets updated to include: https://docs.modalai.com/voxl-datasheets-functional-description/ https://docs.modalai.com/flight-core-datasheets-functional-description/

Have you looked at this doc? https://docs.modalai.com/voxl-streamer/#streaming-uvc-cameras-from-voxl-uvc-server $ lsusb usually helps as well
