This is a basic breakout board for the FTDI FT232RL USB to serial
IC. The pinout of this board matches the FTDI cable to work with
official Arduino and cloned 5V Arduino boards. It can also be used for
general serial applications. The major difference with this board is
that it brings out the DTR pin as opposed to the RTS pin of the FTDI
cable. The DTR pin allows an Arduino target to auto-reset when a new
Sketch is downloaded. This is a really nice feature to have and allows a
sketch to be downloaded without having to hit the reset button. This
board will auto reset any Arduino board that has the reset pin brought
out to a 6-pin connector.The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.
This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.
This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.
One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
This is my first attempt at this Arduino stuff. you can use Ftdi breakout board with an Arduino Pro, and everything will work. The auto reset works fine, and the serial leds are nice for verifying that everything is working. Price is very reasonable.
That’s where the SparkFun FTDI Basic Breakout comes into play! just plug it in, drivers install, and everything just work and continues to work! It’s a new source make fun and enjoy it..
