Hi all,
Can someone make a system diagram of the Skydroid video link? My current understanding is that the Skydroid 5.8GHz Dual Receiver sits near the M12 and connects to a phone/tablet via USB. The same custom Tower app connects to the M12 telemetry via WiFi and UVC video via USB.
At the vehicle air side, are you using the Skydroid 5.8GHz iOS AV Video Downlink? If so, what camera are you plugging into the USB connector?
Thanks!
Hey Greg.
Here is a simple diagram of the M12L connections.
The Handheld unit connects to your phone or tablet via Bluetooth.
The handheld to the R12l receiver via 2.4ghz link.
The Video is a UVC receiver that connects via USB to the phone or tablet. Then leverages a standard 5.8ghz video transmitter that most drones are using at this time.
Hope that helps.
Donât tease us Cao with the T10âŚyou wonât sell me one yet lol
Ricky,
Thanks for Figure 1 as it confirms my understanding of the M12 connections. However, it does not contain the UVC environment. Are you saying that the Skydroid 5.8GHz Dual Receiver (located by the M12) can receive from a video transmitter like an ImmersionRC 5.8GHz unit that transmits analog video?
What is the Skydroid 5.8G iOS AV Video Downlink used for?
Cheers!
Hey Greg.
So the M12l and itâs companion receiver only manage the control and telemetry conversation between the pilot and the drone. The handheld as in the drawing actâs in concert with the handheld via Bluetooth.
To receive a companion Video signal you have the ability to use the Skydroid 5.8g IOS AV Downlink device or similar device like the ROTG as a receiver of 5.8 video signal. Basically itâs just a standard video receiver like the ImmersionRc Dual receiver you call out in your question. The difference is that the Skydroid receiver provides the video to the tablet or phone via the USB connection (UVC Video) and not through the standard Composite Video out method thatâs used for goggles, DVRâs and such.
Like what you see in this image
This video while in Chinese will show you how to use teh receiver in conjunction with the M12l.
The dual antenna version also provides that standard Comp Video out should you want to run goggles as an example.
The Skydroid version of Tower supports this video method (UVC) unlike other apps, Tower and Qgroundcontrol.
Currently there are no versions available to use that have video embedded in the handheld system like say a Mavic. Skydroid has a system called the T10 and that will be made available at some point in the future and it supports the built in video signal. But today you need the separate piece of hardware.
Excellent, thank you!
I wasnât familiar with the Eachine UVC receivers. Iâm not thrilled with powering the device from the phone or tablet. Are there any options here to power it from the M12L or do we need to wait for the T10?
I hope its possible from a usb port from the radio
Hey Greg
I have the same concern about powering the UVC receiver from the tablet.
The SKYDROID UVC Dual Antenna Control Receiver can be powered from an external 5vdc source as well.
the uvc carrier looks really well designed Ricky and nice to look at,yes its a shame we have to wait for the T10 but im sure it will be worth it
Ricky,
Would it be recommended to power the SkyDroid UVC Receiver from the 5v output on the M12? Can you confirm what connector is on the left underside of the M12?
Thank you!
An extra advantage from this radio is long time batts duration :o
Hey Greg.
While I have not given this a try. You would need to mod a USB cable to pull the 5vdc from it and then use a JST type connector for the 5vdc to the UVC receiver.
Then a USB to the tablet from the UVC receiver.
I think the community will need to experiment and see. My concern is having a ton of extra cables all over lol.
Perhaps something like this would help.
So the connector on the left underside of the M12 is a regular USB like on a PC?
I would probably drill a hole in the M12 case and tap into the 5v output for a nice short custom cable to the SkyDroid UVC Receiver JST connector. Since it is only two wires, you could use a simple mini chassis socket from HK.
Might be possible.
Here is an image to show you whats under the hood. Sorry itâs not to clear but you can see what spaces there are that could be leveraged for your suggestion.
Thanks, Ricky. It does look doable from the upper corner. I think it would make for a lower profile than connecting to the USB port on the bottom. Powering the UVC receiver from the M12 would provide less drain on the phone/tablet and utilize the 4AH battery in the M12.
Iâm close to hitting the âBuy Nowâ button. 
Ya I think itâs very possible.
I might crack the case again and see if the connection can be made near the actual UFC holder I designed so you dont have cables all over. I hate mess
Thinking the one concern I have is whether the voltage regulator used in the skydroid would support the extra load placed on it to power the receiver
What is the â5v Outputâ meant for in the first place?
