So... does anybody have a clue what this component is for? It looks like it might be some kind of resistor for the top pad on the left?

I noticed that the one on my board is missing (solder is there, component isn't) - may have never been there, I may have broken it off trying to squeeze the chip into my chassis.
Everything seems to work correctly, but I could probably replace it if I knew what it was.
Got my answer from Erv at Plecter labs (very quick response) - its a capacitor for the sound module.
Easy enough to fix, and much less expensive than buying a new board (or having this one shipped out and fixed).
Rob Petkau (Madcow) has a nice demo on soldering tiny components like this.....
I watched the one Rob has for the wiring, and he mentions another one for soldering components on the board, but I haven't been able to find it.Quote:

I'm not sure the piece has anything to do with the sound though - the board sounds no different to me (and sounds great). But... I think it has something to do with the built in power extender because I get a much better FOC now. Before I could barely see the white flash, but now I can really see the flash.
It was definitely much less expensive, and faster, than replacing or sending the board out to be fixed.
Do you know where this video is located? I looked at his youtube channel and didn't see it.Quote:

Try this link.... It is not exactly the same component as your resistor but it illustrates the technique of attaching very small items to your board.Quote:
