I am trying to install hexTronik MinimOSD between Fatshark and Pixhawk. I know i am getting signal if there is no OSD connected inbetween. If I follow the instructions on the first picture (found on this page: http://copter.ardupilot.com/wiki/common-minim-osd-specific-hardware-setup/ ) the OSD board gets very hot .
If i am trying to power the OSD board with 5V from the APM (see connection schematics on the second picture) i dont get any picture. Are my connections right? Am I supposed to load some firmware on the OSD?

Tried to update the firmware through a TTL converter but i am getting the error message that "cant connect to bootloader". I am thinking of abandoning the OSD idea.
Can anyone help me?
Why dont you try and keep things simple and remove the LCD from the setup and simply have the camera feeding the minimOsd and then have that outputting to the video transmitter. I wonder if the trying to push too many amps thru the little board.
What kind of 12 Volt battery did you use? I only have 3 cell lipos. Would using a regular household 12volt work?
i used tiger 11.1v 900 mah battery. Looks similar to this:

On another note, is it possible to send the video into Mission Planner to overlay the video with the HUD?
Could you elaborate on the "You also need to supply 12v on the video side of the minimosd"?How is your connection schematics?
Mine gets super hot , its on the border of frying the board if I connect it based on the first option in the following link: http://copter.ardupilot.com/wiki/common-minim-osd-quick-installatio...
Maybe it would fry the board if i leave it for long, don't want to risk it.
I am trying to hook it up based on the second option on the link above. The Fatshark transmitter is getting the 12V from the battery trough the voltage regulator. The camera is getting the 5V from the Fatshark Transmitter.
The board seems to get power from the APM side, the three LEDs are on and i can measure 5V on the OSD video side. I tried it with my Gopro too, where i dont need to power the camera. The image comes in clear to the glasses unless i connect the OSD. Tried to enable it in Mission Planner too pressing the green button but nothing happened.
