When I setup and tested my APM 2.5 using the APM Power Module, everything worked flawless. When I connect my MinimOSD it all works fine with video overlay and all. After a short time, everything, and I mean APM 2.5, the ublox GPS, my receiver, and the MinimOSD, all go dead. I can unplug the battery and plug it back in and all comes back for a short time (1 to 2 mins.) then dead again. If I unplug the OSD all is well again. The system will run for any amount of time without issue.
Is the power module having a bad time with powering the APM 2.5, my receiver (Spektrum AR8000), the external GPS, and the MinimOSD? I am using a 3 cell 3300 mAh lipo for my main power and nothing else is providing power at this time. I have a Castle UBEC that can be added if that will solve my problem. If so will I have to take the APM Power Module out of the system? How can I still use it to measure voltage and amperage draw from my pack if I use another power source?
Yes, I am a newb. Please help.
P.S. I also noticed the MinimOSD processor gets somewhat warm to touch before the system dies. Is there maybe something wrong with it causing my issue? It works fine right up to just before the system shuts down and then the display overlay gets corrupted. I figured this might just be voltage drop right before the shutdown.
