Is there a way to access the kernel serial debug port on M0090? It seems there are FTDI components but they are not populated.

@tahawaru Here is some documentation on configuring VIO https://docs.modalai.com/flying-with-vio/

PX4 does not currently handle GPS and VIO concurrently. It is something that we have worked with the PX4 developers on for more than 2 years.

It's a complicated problem though that we keep working to improve. To start experimenting, and hopefully helping to develop that feature, read through PX4's documentation on EKF2.

To debug VIO, look to this area of the documentation specifically https://docs.modalai.com/flying-with-vio/#troubleshooting-vio

@Jetson-Nano Looks like MPC_POS_MODE is needed as well per the documentation https://docs.px4.io/main/en/computer_vision/collision_prevention.html

We have updated the M0129 in the past few months to support 2S-6S, it looks like the datasheet is out of date. Thanks for pointing that out.

If it is marked M0129-63 or M0129-65 it supports 6S

M0129-3 and M0129-5 are the older version and they only go up to 4S

When making a request for support, there are some key pieces of information that really help speed up the support process. Please try to include the following when making a request:

• What hardware are you using? If you have specific SKU or serial number, that is also helpful
• What version of software are you using? voxl-version is very helpful for determining software version.
• How have you configured the software? What is the output of voxl-inspect-services
• Do you have any logs? Uploading PX4 logs to https://logs.px4.io can be very helpful. See details on PX4 logs here
• Can you share pictures of your setup?
• Have you looked at the source code? If so, can you point to any potential issues?

If you see the sensor in the portal, you have the sensor configured properly.

By fails to calibrate, are you using voxl-camera-calibration ?

if you viewed the data through voxl-portal, it would already be rotated properly.

The Starling's extrinsic parameters can be found here, which should help you configure your URDF

VOXL 2 Mini USB OTG negotiates automatically. There should not be a special cable required for VOXL 2 Mini

VOXL 1 required a special cable and VOXL 2 OTG does not currently work

@Sanket-Shah voxl-inspect-cam can be used to verify it's working and see related stats. You need a GUI of some kind to actually view the image, which requires a network

@tiralonghipol if you viewed the data through voxl-portal, it would already be rotated properly. It's not clear which viewer you are using for the data.

The Starling's extrinsic parameters can be found here, which should help you configure your tools

@wilkinsaf unfortunately, we don't have M0024 step file

For IMX412, we do have the M0107 which has step file https://docs.modalai.com/pcb-catalog/

@david-moro Yes, the VOXL 2 Mini supports OV9782

@Sanket-Shah Hi Sanket, the M0107 wasn't fully supported until SDK 1.1.0. See this page to upgrade https://docs.modalai.com/flash-system-image/

Sorry for the inconvenience. We do screen for focus, this one may have slipped through. Please see attach focusing guidelines from our production team https://storage.googleapis.com/modalai_public/temp/MODALAI-Focusing-M0014-160823-043819.pdf

you can see this post regarding "Avionics Power Low", in short you can ignore it https://forum.modalai.com/topic/2051/avionics-power?_=1716249395852

You should definitely not be powering Flight Core with USB. The APM is far more capable.

What R/C are you using? This sounds much more like an RF issue than a Flight Core issue. If the Flight Core logs are valid, then it's running fine.

1. Do you have the 3D CAD files for Sentinel?

2. Do you have the 3D CAD files for Seeker?

voxl-mapper has been working on VOXL 2 for about a year. It should work out of the box on a Starling.

What you may be referring to is better documentation for using with stereo sensors instead of TOF sensors, but in general the voxl-mapper package is working.

This video shows how it works - https://www.youtube.com/watch?v=gqlSKRP8prc&ab_channel=ModalAI

@Mariano-GOMEZ-PLAZA have you looked at this documentation? https://docs.modalai.com/voxl-uvc-flir/#overview

@Jgaucin voxl-tflite-server is just a wrapper for standard TensorFlow Lite that has been compiled with the proper configurations to take advantage of QRB5165.

voxl-tflite-server code

So, if you can achieve what you are trying to do using TensorFlow Lite on the desktop, then you should be able to bring over to VOXL 2 in a straightforward manner.

The inference_worker function here is where the models are processed

I ordered a Flight Core V2 PX4 FC from you guys several weeks ago and I've been studying the datasheet. What connector would I use for a servo? Thanks.
