We have updated our docs here: https://docs.modalai.com/doodle-labs-user-guide/#voxl-2-10-pin-usb-add-on-boards

@Moderator If you can provide the serial number of your VOXL CAM (form MXX00000XXX) we can check to see if we have the camera calibration data backed up in our production database and provide it if so.

You can find that in the 'D0011 Starling PX4 Edition March 21 2024.STEP' found here: https://developer.modalai.com/asset/6

@Eric-Katzfey
Thak you for your information.

Should I check following DOCS?right?
https://docs.modalai.com/voxl2-rc-configs/

@Moderator
From a software viewpoint, yes, they should be identical due to the USB Host port connectivity.

However, the reason why Doodle is not listed as one of our connectivity options on VOXL 2 Mini is due to power limitations.
The VBUS of the USB Port J3 can only provide 900mA, which is less than 1/2 of what a Doodle radio asks for (most Doodle radios need 5V @ 2A).
To try to use a Doodle on VOXL 2 Mini will require you to connect an external power supply as per Doodle's requirements and then use our USB connector for GND, D+, and D- only.
Be sure somewhere in the system, specifically at the Doodle connectors, to connect the GNDs of the power supply and our USB GND to create a common DC GND reference, but to not introduce noise from the power supply into the USB signals.
We do not normally do this, so we are not aware of any other caveats, but we can't guarantee 100% success either.
Give it a try!
Let us know if you need further guidance.
Thanks

The Flir Lepton feature is still in development. Please check future release notes in VOXL SDK for updates on availability.

@Devang-Dhake That is interesting, I was able to get the parts separated and uploaded. Here is a link to download a zip file containing an A and B stl.

@Moderator No, it does not. You need to rely on QGC or other reporting tools.

@Moderator You can find it embedded in the Sentinel 3D Model found here: https://docs.modalai.com/sentinel-functional-description/#sentinel-3d-step

@Moderator said in VOXL ESC Mini 4-in-1 Current per Motor:

Is it possible to step up voltage?

Can you please clarify the question? 🙂

Mini ESC is designed for small drones ( < 500g ). The ESC has been tested to handle 15A continous at 15V input continuously (60+ seconds), but with full direct air flow from propellers. This would simulate a full throttle "punch-out" on a small FPV drone (high current, but also lots of direct airflow = cooling). Do not use this ESC if the drone needs 10-15A per channel just to hover. Use it in application where hover current per motor is less than 5A (ideally 2-3A which is very typical) and absolute maximum continuous current per motor can be 10-15A.

For example, motors used for small FPV drones often are around 1306 size (3-4S Lipo). Those motors are usually rated for up to 10-12A continous (for 30-60 seconds). Larger motors can be used as long as maximum motor current does not exceed 10-15A (still 2-3A at hover) and there is sufficient cooling.

Always check ESC board temperature during initial flights / tuning. Temperature must stay below 110C at all times (critical), typically in the range of 40-70C for most applications. The ESC will most likely fail above 125C.

Temperature of the ESC board is the limiting factor because the board is so small. Mosfets can handle a lot of current as long as they don't overheat. So the design of the drone is very important (either use low current so that temperature is not an issue or properly design air flow from propellers and/or add heat spreader to keep the ESC board temperature in normal range for higher current draw applications).

ESC provides real time temperature feedback and it can be viewed in PX4 / QGC. Additionally, the PX4 logs contain the temperature information.

Yes, the Qualcomm Flight RB5 User Guide will send you to the 5G modem user guide if you are using the latest software.

We do not have a clean solution for this combination of parts since VOXL 2 Mini does not have a 5V power module. The approach will be "clunky" at best at the moment by using an additional 5V power source somewhere in your system.

When our Voxl2 dedicated version of the new ToF adapter is ready (M0171) we should have better integration to support at least 1 ToF module using our on-board 5V regulator, but it will be limited to only 1 ToF, and may prevent high-current USB use cases.
Once we have the working solution(s), we can explain better.

Please stay tuned.
Thanks!

@Matthew-Wellner FYI

@AP123 What was the resolution to this issue? My team is experiencing a similar problem. Were you able to access the microhard web portal through the VOXL 2?

Please refer to the mavlink routing documentation here: https://docs.modalai.com/mavlink/#mavlink-routing-on-voxl

@Moderator Thanks for your response. I didn't realize that the VOXL CAM is actually a combination of VOXL companion computer and camera module. My drone uses Pixhawk 6C autopilot, I have a companion computer connected to its TELEM2, now I am looking for tracking camera. If I use VOXL CAM, will the VOXL computer conflict with the computer that I am currently using? If not, which port can I connect VOXL CAM to? And what settings need to be made, do you have a manual/instruction for the setup?
