This board converts a USB connection into 5 volt TX and RX that you can connect straight to the Arduino Mini or other microcontrollers, allowing them to talk to the computer. It is based on the FT232RL chip from FTDI.
Description: This is the newest revision of our FTDI Basic. We 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.
It worked but now I can`t send or get any traffic throught it. I am using it for NEO-6M gps. Windows don`t recognize it and power LED does not flash. But it still powers the gps, which is new. What could be wrong?
I'm not sure waht are you trying to do... To check adapter connect it to USB. Check device manager for com port number (com over usb). If no port appears then this might be driver problems or dead adapter... if new com appears in device manager you can open this port with any terminal program (like putty for example)... Connect TX and RX pins on adapter. After this typing any char in terminal must be echoed back in terminal window through adapter...
Ótimos, com bom acabamento e compatíveis com o Arduino, pois tem o pino DTR que é utilizado para o reset.

Great and cheap little USB <-> RS232 converter (TTL voltage level). I soldered one into my Multiplex mc3030 transmitter, connected to its internal serial port. So I can backup the model memories with just o USB cable via laptop (additional software mc3030-manager required).
Just ordered more of these...
