This Triangle D DVR/Vtx board does an amazing number of functions, with a VERY small footprint! So far I love all the features, except for the fatal flaw my unit demonstrates... it does not produce any video with the compatible Eachine 1000TVL CCD camera that is advertised to take 5V input. I get a black screen with the goggle OSD text, but no image and I have used 3 different CCD cameras that work with other VTx boards with no success. Measuring the camera port output with a voltmeter: My test results follow: 1) Triangle powered by 3.8-4.2v LiPo @ 4.11v supplies 4.09v to camera port 2) Triangle powered by 5V ESC using receiver line @ 4.94v supplies 4.92v to camera port, but neither source gives a video signal with the Eachine 1000TVL CCD camera. Does this board boost input voltages less than 5V? If so, it isn't working on this board. What is the absolute minimum voltage that will work with this board? Must be somewhat less than 5.00 volts. Perhaps my board was a one-off fluke. I have ordered 2 more boards to try, and have asked Eachine (on their homepage review section) for help, but none has been provided), but I will be asking BangGood for a refund on this one or to mail me a replacement. This would be a very well designed board if my inability to produce video is not a common problem with other boards.
