I have a MinimOSD all wired up correctly and working properly, I think, but there is one issue with it. All of the telemetry I need for the most part works (like arming and disarming) except for the battery voltage? It is constantly displaying 17ishv when my quad is only connected to a 3s? I have the tx,rx,gnd and 5v all connected to the cc3d and the pass through for video gnd and 12v also connected. I assumed it got it's voltage data from the 12v connection but I am just now finding out that this isn't true. Does it get it's voltage data from the cc3d? I feel like I'm missing something obvious to get this thing to work right, any help would be much appreciated.
