Hi all. Basic question I think. What would be the best way to power a 5V 500mW VTx. Is there a 5V point able to supply enough current or should I be using a dedicated ubec?
Thanks for your advice.

This is really a nice OSD, I have used an EagleTree Pro & Remzibi for 2 yrs now, yours is next on my list (no funds right now) I will need 2, For TM stream, I tap into port 0 for xBee, OSD on port 3 both have two way comm, works well for me. I monitor various data fields on the screen while troubleshooting issues. Helps a lot. You have a winner!

@George, is better to use an external uBEC. What camera are you planing to use?

One more question now that my shiny new cable has come in: how is the FTDI cable to be connected to the MinimOSD board?  Was that written up somewhere in the FAQ and I missed it?

Thanks Sandro, uBEC it is then. I had intended to use a board camera as per the specs below, however I expect it not to be compatible with the graphics chip as indicated in some other thread I read somewhere because of its resolution. If that is the case it will be a trusty KX171.

FH32HQ1 is a low cost camera designed for FPV use, it adapts light changing very quickly, good color and good image quality.

@Mark, glad you like it! =) I hope you can get yours soon.

Developer Comment by Sandro Benigno on February 23, 2012 at 3:46pm

@Vaeddyn, one side of your MinimOSD has exactly the same pinout of your cable (six pins).

Those pins have even a reference to the colors of your FTDI cable: "GRN" means "green wire" and "BLK" means "black wire".

Comment by vaeddyn on February 23, 2012 at 3:48pm

So the same pins that the MinimOSD normally connects to the ArduPilot board with?

Developer Comment by Sandro Benigno on February 23, 2012 at 4:23pm

@Vaeddyn: Yep. The same ones.
