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 3.3V 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 DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.
There are pros and cons to the FTDI Cable vs the FTDI Basic. This board has TX and RX LEDs that allow you to actually see serial traffic on the LEDs to verify if the board is working, but this board requires a Mini-B cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal.
This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro and LilyPad boards use this type of connector.
Note: We know a lot of you prefer microUSB over miniUSB. Never fear, we’ve got you covered! Check out our FT231X Breakout for your micro FTDI needs!

I had the 5V version of this and needed the 3.3V version for my Arduino Pro Mini boards.
I have used this for the Sparkfun pro mini board (it will program the 5v board also) and other boards with FTDI headers. Notably the Adafruit trinkets (sorry sparkfun - I try everything). It also works in a pinch as a serial to UART board. Just wire it directly to any UART device (I use it to test XBees sometimes) and you can use the Arduino IDE to send serial data.
No problems at all with this little guy. Worked exactly how I expected it to.
Works well. I wired by hand and had a mistake that wasted an hour :/ maybe it is worth buying a pre-made cable assembly for the UART portion.
Works as it should, as long as you use the FTDI drivers, not the ones built into OS X. The built-in driver has issues with leaving DTR low.
