Another New PCB for Arduino Serial Single Sided

I removed the post with links to the revision 0 to don't make confusion.

So, repeating:
Revision 0:

I did one more change. The board was full compatible with shields, but the jumpers (auto reset enable and serial enable) where making compatibility difficult (when to remove or changing them where necessary). So I changed jumpers to right angle type. The jumpers now are removed by side, not top.

The Serial enable feature is working fine. And the onboard pull down resistors too. Now I think they're extremely necessary.

Revision 1:

I put a low pass filter on AVcc, as described on Atmega datasheet, and on forum here http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1180835996

This feature can reduce the noise on analog pins, and on ADC, since it can be connected internally to the Aref.

I renamed some components to make it easier on finding them on board. So the Part list changed too.

And the Preliminary Beta Arduino S3V3rino Revision 1 files are:

(two .png files, for top and for bottom)

The only thing I ask is to keep us informed about any malfunction or trouble. Tell us if is it working well too. Remember: it is only a preliminary beta version. I hope it works well, like with me (note that I couldn't make the Bootload on Arduino version 2 or beta3 work well with Arduino 0010 software version, only with 0007, so I ask you to try this version (0007) too, while testing it. I think it's a software problem. I am already talking to Mellis about it. To upload sketches with 0010 is ok.

Good luck.
