Tarjeta FTDI convertidor usb - serial para Arduino 5v
Descripción: Esta tarjeta contiene un FTDI FT232RL para conversión USB a serial. El pinout de esta tarjeta es idéntico al de un cable FTDI para trabajar con tarjetas Arduino a 5V. También puede ser usado para aplicaciones generales que involucren un puerto serial. La principal diferencia de esta tarjeta con respecto al cable FTDI es que tiene el pin DTR en lugar del RTS. El pin DTR te permite que el Arduino se autoresetee cuando lo programas. Esta característica evita que tengas que presionar el botón de reset cada vez que le quieres cargar un nuevo programa.
Los pines BLK y GRN corresponden a los cables de colores en un cable FTDI. El cable negro es GND, el verde es CTS. Emplea estos pines para "alinear" los pines de esta tarjeta con tu Arduino.
Esta tarjeta posee LEDs indicadores de TX y RX lo que te permite ver en tiempo real el tráfico serial y asegurarte que está funcionando correctamente.
Esta tarjeta fue diseñada para disminuir el costo de desarrollo de Arduino ya que te permite adquirir tarjetas de bajo costo como Arduino Pro y LilyPads que no poseen interfaz USB serial integrada.
Así mismo posee un jumper para configurarla a 3.3V o 5V tanto en niveles de alimentación como en I/O. El default es de 5V pero puedes cambiar el jumper para switchearla a 3.3V.

FTDI Basic Breakout - 5V
DEV-09716
Description: This is the newest revision of our FTDI Basic. We now use a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same.
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.
