How can I transfer an image from raspberry pi to this thing?

Question

Robotics

I have such a thing, this is a viewfinder, directly from the FatShark Teleporter v3 fpv glasses


and scarves to it, it itself connects to the middle scarf, to the left of it is a board with power and AV input, to
the right is a board that receives a signal from the transmitter (essentially not I need it at all)
The viewfinder is connected via 7 wires to the middle board, on the viewfinder itself there are two small screens that are connected to its board.



Here is the battery powered circuit.

I want to connect it to raspberry pi v4 and stream video. There are a few ideas about this
1) Use the av output from the raspberry pi and the input on the glasses themselves
- cons : You have to use this whole set of boards, which I don't really want to do in my project
2) Ask here how this can be done, perhaps not using the middle board and the board with av input, but figure out how to connect directly to those 7 wires, along with power

Answer 1

Perhaps the board to which 2 displays are connected is self-sufficient.
On the 6-pin black harness, look for where the power is, + and -
Perhaps there will be several supply voltages.
Next question, stereo glasses? Then there will probably be two video inputs, one for each eye.
In general, according to the layout of the board, it will be more or less clear where there is power and where there is a signal. But the pictures are shit and you can't see anything.
Because the glasses seem to be working, you can turn it on and measure the voltage at the connector to make it clearer.
But if your hands are not shaking, then the probe will jump off and shorten tightly.

Answer 2

I'm not an expert, but it seems to me that you need to send a signal to the middle scarf, because she already knows how to "communicate" with the glasses and "transmit" a picture to them ... or solder the wires from the glasses and figure out which one is responsible for what ... but I personally wouldn't be able to do that.
