Could someone tell me what controller(s) these HDMI modules are for?

Putting the reference number of the top left board into a Google Search seems to indicate that it's for a Phantom 3/4, which is also the same board as for the Inspire 1.

Maybe you could try doing similar for the other pcb identifiers and see what comes up?

In the case of my P3P, I added one of these so I could connect DJI Goggles.

@Mdeblasi1991

I saw that you made another post, then seem to have changed your mind and deleted it.

Unfortunately, I think that it's fairly unlikely that you're going to find someone here who has an encyclopedic knowledge of DJI HDMI boards, their reference numbers, physical appearance and usage. Like many here, I installed an HDMI board in my controller, checked it worked OK and then forgot all about it

I fear that you are going to have to do some spade-work yourself, with quite a lot of spot-the-difference puzzling and trawling to find and compare multiple images, both here and on the WWW.

However, if anyone else is able to step up and help, then please do...
