Get it as soon as wed aug 26.
If we look at the schematic of arduino we will see that the rx and tx pins are connected to the ftdi chip as we expected on arduino board as pin 0 and pin 1 that means we can use those pins for using the ftdi chip itself.
Theoretically they could be programmed with an rs232 port but it is really hard to find a pc with rs232.
So these arduinos require a usb to ttl converter.
The cables provide a fast simple way to connect devices with a ttl level serial interface to usb rx and tx leds indicator the cables are available with a 6 way sil 0 1 connector ttl levels is 3 3v the ttl 232r cables are a family of usb to ttl serial uart converter cables incorporating ftd s ft232rq usb to serial.
