Can this board be used to upload sketches to the Arduino. I tried by hooking the TX port on the FTDI Basic Breakout to RX port(Pin 2 on the Arduino) and RX port to pin 3 on the Arduino. But so far I am not abl to upload anything.
The driver for the board loads fine.
Thanks for any feed back.
As Joby Taffey suggests, the rx & tx pins of the AVR are 2 & 3 respectively, but on the Arduino headers they are pins 0 & 1. You also want to connect DTR to the reset pin of the arduino to enable automatic programming.
FTDI Arduino
Breakout (5V)
GND <--> GND
CTS <--> (not connected)
5V <--> 5V (if you want the breakout to power the arduino)
TXO <--> RX (pin 0)
RXO <--> TX (pin 1)
DTR <--> RESET (possibly through a 100nF cap*)
On the FTDI TTL232R cable, DTR is not present so you have to manually reset the board before flashing. By default the Arduino will stay in the bootloader for 6-8s, but some boards rely on the automatic reset and have much shorter timeouts (0.25s say). For these boards, set upload.verbose = true in your Arduino conf file, and learn to time the reset the moment the software attempts to flash the board.
This board can be used to connect to the Arduino and transmit serial data, yes. I don't know much about how the Arduino loads sketches, but here's some suggestions:
Check your pins for TX and RX, this diagram suggests that they might be labelled "pin 0" and "pin 1". But, this may depend on your make/model of Arduino.

Check that the FTDI breakout's Ground is connected to the Arduino Ground pin.
Check that the Arduino is powered up.
