Description

This is a dual camera 5" Quadcopter build with a Caddx Ratel pro and a Thermal Camera which can be switched between. This uses a DJI original Air unit and a NeutronRC Converter board allowing for use of Digital FPV.

I used a small AIO FC/ESC because there a a lot of parts you have to cram into this thing. You need an RCA to HDMI board which plugs into the DJI Converter board. In the parts below is the one i used which I found on amazon. Its the smallest one I could find but still kind of big. Its important that its 720p. I first used a smaller one with only 1080p and it made the video super zoomed in and un-usable. 

If you would like some more info about the wiring diagram of the build this reddit post was very helpfull with building:
