Thank you so much.

@Vinny
Please let us know the results of your USB3.0 port test.

Thanks,

@Vinny
I hope you find a solution.
We are already using V2 for VTOL drones, and are planning to use V2-mini for other large-scale projects.

Thank you,

1. We conducted a comparative test on the VOXL2-mini USB3 port HW issue as follows.

1)Test equipment

• VOXL2+5GModem (USB3 port) and VOXL2-mini (USB3 port)
• Arducam 13MP IMX258 OIS Motorized Focus USB 3.0 Camera Module

2)Test results
In conclusion, after removing the VOXL2-mini USB3.0 cable, the same problem appears as a result of testing. (Only 1280x720@10fps is supported.)

a. VOXL2+5GModem (USB3 port)

b. VOXL2-mini (USB3 port)

2. Question

1. When will the board with the VOXL2-mini AC Capacity problem solved be released?
   (We need to use the USB3 port. We need to purchase 3 units right now, but we are unable to purchase them due to the AC Cap issue.)
2. After purchasing VOXL2-mini, is it possible to replace the product if an improved version comes out?

Thanks,

@Jskim

We tested it using a USB30 to USB2.0 cable.

1. 1280x720@10fps is no problem.
2. 1280x720@30fps does not work.

Thanks

@Eric-Katzfey

Sorry, please tell me again how to add capacitors.

Thanks,

@Eric-Katzfey
Thank you very much for the quick reply.

1. When I executed the voxl-uvc-server -d command, the screen froze.

@Eric-Katzfey
Thank you for your quick reply.

I have a problem with the VOXL2-mini USB3 port.
When I connect a USB3 camera directly to the VOXL2-mini, the camera is recognised but no output.
However, when we change the USB3 to USB2, the camera output is only 1280x720@10fps.

2. Correct. we want a minimum of 1280x720@30fps.

3. voxl-uvc-server is running. But no output is displayed.

4. what happens when you change 10 to 30?
   A) When you change to 30, there is no output.

Thanks,

@Vinny
Thank you so much for your quick reply.

1. The HDMI to USB dongle is powered by USB3 from the VOXL2-mini.
2. We have no problem using the TP link wifi dongle on the USB3 port. I have already tested it.

3. We will tell you the results of the test with the arducam USB3.0 camera.

1) You need to check whether the problem is with the USB3.0 port or the streamer or the uvc server.???
2) You can see the voxl2-mini test result in the image below.

*Note: We use USB3 to USb2 conversion, 1280x720 @10fps no problem.

4. We tested arducam directly connected to Windows PC USB3 port and there is no problem.
   

Thanks,

@Vinny

1. That does not look like our standard MCBL-00022-2.
   A) This is the same cable as MCBL-00022-2. It is wrapped with insulating tape.

2. Did you do some additional splicing/merging to make this connect to the HDMI adapter? Did you add the series caps needed on TX (output) for USB3 speeds?
   A) This is a standard cable purchased from MODALAI and no work was done.

3. https://docs.modalai.com/voxl2-mini-connectors/#j3-usb-3-10-pin
   Did you remove the USB3 lines altogether? (USB2 is plenty of bandwidth for most video applications)
   When we use a USB2.0 adapter on the VOXL2-mini USB3.0 port, only 640x480@30fps is supported.
   A) We need uvc camera resolution 720p@30fps. The USB2.0 supported resolution is only 640x480@30fps.

4. Can you also please share the specs of your HDMI adapter and HDMI camera as well? I'm curious how that is working from a hardware standpoint. You could be missing some power features here to power all these adapters correctly, making the link not work. I'd like to help double check for everyone involved.

1) HDMI adapter maker and model name : Anyport & AP-HDC4K
2) HDMI camera maker and model : MOHOC &MOHOC(https://www.mohoc.com/)

5. We have purchased and are testing an Arducam USB3.0 camera.
(Arducam 13MP IMX258 OIS Motorized Focus USB 3.0 Camera Module)

1. Format : YUY2
2. Frame Rate (USB 3.0) : 1280720@60fps,19201080@40fps,20961560@30fps,38402160@20fps,4208*3120@12fps
3. Interface : USB 3.2 Gen 1 device, backward compatible with USB 2.0 hosts
4. UVC Compliant : No additional drivers required

Thanks,

@Eric-Katzfey

1. The documentation for voxl-uvc-server is here:
   A) I fully understand the contents and am using the UVC camera without any problems.
   I think that's beside the point. We are talking about HDMI cameras. (When using an HDMI camera, 640x480@30fps and 1024x720@10fps operate without any problems.)

2. The problem mentioned above is not a UVC camera problem, but that the HDMI camera does not support FHD and HD on the VOXL2-mini when using the USB3.0 to HDMI adapter.

3. System configuration diagram:
   VOXL2-mini (USB3.0 Port) -> USB3.0 to HDMI adapter -> HDMI camera

4. Questions

1. When using an HDMI camera, does VOXL2-mini not support FHD (@30fps) and HD (@30fps)?
2. If support is not provided, what is the reason?
3. If supported, what is the connectivity solution?

5. Notes

1. MIPI CSI-2 cameras are mainly used for very small drones, but
   USB, HDMI, and IP cameras are mainly used for medium-sized and larger drones.
2. We are testing an H.265 IP camera using an Ethernet adapter on the USB3.0 port of VOXL-mini. I will ask additional questions once the results come out.
3. I will share the USB3.0 camera test results.

@Jskim
There were no error messages.
640x480 @30fps is fine.

@Moderator
There were no error messages.

1. We have tried to test the HDMI camera using USB3 To HDMI Adapter.
   -HDMI camera resolution: 720p @30fps
   -Camera model : MOHOC
   The test result is that uvc server is not running.

The uvc server only supports 640x480@30fps or 800x600@10fp.
2. Is there a problem with uvc server? or am I configuring it wrong, I don't understand.
The conclusion is that the uvc server cannot support HDMI camera FHD, HD.
3. I ordered a USB3.0 camera. Finally, I will try to connect the USB3.0 camera to test it. (Arducam 13MP IMX258 OIS Motorised Focus USB 3.0 Camera Module)
4. All drone users need to connect various cameras (IP camera, HDMI camera, etc.) via USB, but it seems that VOXL2-mini does not support it.
5. I spend too much time connecting cameras.

(Question)
Please let me know if there is a solution to the above problem???

Thanks,
