  @jefersonsilva If you let it sit for a long time does it eventually find satellites and get a fix?

  @extmoddrv

  We support the following modes for IMX412 cameras:

  Full frame 4056x3040 : 30FPS, possibly 60FPS (need to double check) 4K 60FPS 1080P 180FPS (maybe 240 FPS, need to double check) 720P (cropped) 240FPS

  AR0144 FPS is currently limited to 50FPS (camera maximum is 60fps, but we have seen some stability issues). Resolution for AR0144 is fixed at 1280x800.

  If you provide your specific requirements, I can confirm whether that is supported. Are you looking for the h264/5 encoded video for IMX412 camera? What about AR0144 tracking cameras - just RAW?

  So I have a VOXL2 and have it connected to my linux server currently that a client sent me.  Im able to connect via usb adb but it does not have internet access.

  Also I followed https://docs.modalai.com/voxl-portal-via-adb/. These instructions to get access to the portal on the localhost but I cant curl or navigate to it via browser. I tried this on a few systems.  Is there a way to get the voxl 2 to use USBc to act as a bridge to communicate out to the internet? I am able to get it to ping my Ubuntu server I have it plugged into via tcp but the Ubuntu system caan not return any communications.

  Any advice on this? Using the wifi module is not an option since it has a custom hat soldered to the top of it. I need to install a few python modules on it such as ultralytics and the rebuild a few things to support some custom vision models and being able to access the webserver to test them would be nice.

  Thank you for your time.

  @plub , could you please clarify which cameras you are using in the stereo configuration? OV7251?

  If the larger pattern was still detected by the procedure but was not accepted as a sample, this means that the pattern took up too little space of the desired area. You need to fill the desired area in each step almost completely, so that the sample is accepted.

  Also, is your checkerboard printed on paper and attached to a very flat surface without wrinkles? A poor calibration pattern can lead to poor results.

  Can you please post the result of the calibration? intrinsic and extrinsic parameters that are generated by the calibration procedure, even though it fails. Also please share the reprojection errors.

  @Jetson-Nano , the following link shows location of all the connections and test points that are being utilized: https://docs.modalai.com/voxl-fpv-esc-datasheet/#hardware-overview . If there is a test point that is not documented, it means it is not supported in firmware or only used for production testing. If you have a specific question, please let me know.

  The following link describes the Neopixel led support : https://docs.modalai.com/voxl-fpv-esc-datasheet/#neopixel-led-support . A single string with up to 32 LEDs is supported. VAUX regulator is dedicated for this output and can handle 500-600mA. We also have a way to control this output to be 3.3V or 5.0V (3.3V default) but the control feature is disabled at the moment. You can test the Neopixel output while PX4 is not running using voxl-esc tools : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/voxl-esc-neopixel-test.py (we also have a helper command to use the LED while PX4 is running). https://gitlab.com/voxl-public/voxl-sdk/services/voxl-io-server/-/blob/master/tools/voxl-send-neopixel-cmd.c -- this tool is a command line tool which sends the control data to PX4 and then PX4 forwards it to the ESC. Right now the C example only supports white color, but we will extend it to RGB.

  The payload connector just outputs VBATT, so as long as your desired current is within the JST connector spec, you should be ok. (4Amps per manufacturer's spec).

  J1 is used for UART communication with FC or the voxl-esc test scripts and the data that is send are the ESC commands (rpm or power) and other commands like Neopixel commands, PWM output.. The ESC also sends back the ESC status.

  Let us know if you have any more questions 🙂
