Description: This is the SparkFun USB to Serial Breakout for the FT232RL, a small board with a built in USB to serial UART interface. This little breakout is built around the FT232RL IC from FTDI, with an internal oscillator, EEPROM, and a 28-pin SSOP package this is a serious little chip.
With this version, we’ve corrected a few issues found with the board. These changes include fixes to the VCCIO, a change from the mini USB to micro USB connector, and a few footprint modifications. Other than finding this board much easier to use, it is still the same FT232RL breakout that you know and love!

The board worked perfectly as designed but I had to do one hack first. The I/O voltage is only selectable between 3.3 and 5V while my processor runs at 2.5V. I had to remove the switch and add a provision for an external I/O voltage input. Adding a pad and some sort of jumper, etc. for this would be helpful. Thanks at least for providing the schematic, it made the mod very easy to do.
This little breakout board came with everything needed to assemble in various configurations to fit your need. The board worked exactly as advertised, and was a snap to set up after assembly. Love the documentation provided at Sparkfun–best in class.

Beware this does not use a standard USB mini cable. I needed to steal my wifes phone cable to fit.

Works well, but doesn’t seem to support 1.8v even though the IC is capable of it: http://www.ftdichip.com/Products/ICs/FT232R.htm
It is simple and it can still do all you need it to, best thing is it just work. I use it both in teaching my electronic class and development of satellite instrument. At DTU Space Denmark Best Regards Thorbjørn H. Christensen
I have this board connected directly to an ATMEGA32 chip for debug. It works great, simple to hook up. Uses universal FTDI drivers.
Easy to implement. Works great for interfacing UART and USB.
Board itself works okay but as this is first time I am using this board I had problem finding the correct pin connections to the other board (BT module) I am using in my project. The data sheet available in your page shows all but the simple connection diagram for 2x9 pins + additional 4 pins.
I’m sorry that it wasn’t easier to find the information you were looking for. We try to cover as much as we can in our docs, but we can’t always get everything. Happy hacking.
There are much cheaper bridges available in bulk from Alibaba and Ebay, but usually they’re based on the SiLabs CP2102.
Pros: Dual mode drivers - You can use as VCP or direct mode. Great DLL documentation and source code examples for many platforms. DLLs to go with that great DLL documentation. Respectable support department has been responsive even to my hobby user questions. One set of drivers works with serial, JTAG, FIFO, other variants of the FTDI chips.
Cons: It’s a wee big for hobby projects where space is tight. There are some Silabs boards that are ½ or 1/3 the size. This board is pretty easy to cut down without worrying about damaging anything though. Price - You can get equivalent function for serial only for $5 or so elsewhere, but you may have the occasional defective card.
Bottom line: FTDI chips are well supported and documented. You get piece of mind that your project will just work - the first time, every time.
Everyone who works with microcontrollers and sensors should have at least one of these in their toolbox. It took me 5 minutes to connect this to a sensor and I was up and running.
