For future reference, these are M1.2X2mm 25 pitch. They are available on EBAY for about $8 per hundred. The V! Pro camera worked perfectly on the V2 "Enterprise" version drone. The V2 Dual camera just did not work on the V1 controller and the IPAD. It recognized that a thermal camera was there, but would not display any image or even send pictures or video to the card. It also didn't show on the controller, when I tried to use that screen. I just got a black screen on the IPAD and one of those permanent wait-rolling-icons on the controller screen.
I wanted to use the controller and the enterprise version for general work because they really are different. The screen is easily readable in the sunlight and the drone, contrary to what I've read, holds up much better in the wind (probably due to the larger motors, props, and lighter arms. I flew it yesterday and the tower, that I had to work with, said they were at reduced operations for the wind and he didn't think drones would be flying that day (gusts to about 30 mph). I had to fly for an hour monitoring a point, and it was two batteries. The thing was rock stable, unlike my V1 Pro version or my Phantom, which would have been all over the place.
