I’m trying to install a 3DR MinimOSD board on my hex. I’m using a Fatshark camera/transmitter and an independent 3S battery. It’s all hooked up just like this:
I plug it in, and only get a grey screen. No video, no OSD overlay. Two red lights on the OSD board light up. When i hit the reset button on the OSD another light flashes green. I’ve triple checked the camera/transmitter without the OSD hooked into them and they both work well. Is this a problem with my OSD board, or am I missing something? I bought it right from 3DR, but before I try to return it, I wanted to make sure I’m not missing something.
Thanks Mark. Yes, all the gear works perfect without the OSD. I tried connecting the solder jumpers and taking the 12v off the board. No luck. Just a grey screen. Sounds like a dud. I think I’ll be returning this to 3DR.
Might be a silly question but are you powering up the apm/pixhawk as well?
My goggles show static to start with followed by a grey screen when I power up the vtx and osd, and only showing the cam/osd feed when the pixhawk battery is connected.
