Why does the one on the left have a Sony logo?

That one installs a root kit onto your PC, at no extra charge.  ;)

Just solder a .1 cap from the DTR hole pad to the base of the RST connector pin, turn the board over and cut the trace that was going to the RST pin, and you gain arduino auto-reset.


Just checking (as I'm a newbie) - are you saying one of these

plus quick modification and home-made pinout adaptor and you've got yourself a cheap FTDI setup to program chips with bootloader?

I think it is harder to brick a chip by using bootloader from my experience

Yes, I have tested that and it works fine. Of course the serial cable does not use the FTDI chip so a different USB driver will be required when you first plug it into your PC. I think my XP found a driver automatically but drivers for the chip used are easy to fine.

Windows Vista SP2 found the CP2102 driver & downloaded(?)/installed it all by itself when I connected that module.

Lefty,
Adding a cap isn't needed if the board has one already, is it?
