The FTDI Friend is an improved FTDI FT232RL chip adapter. Like the well-known FTDI cable, it can provide power to your project and there are 4 signal lines for sending data back and forth. But the Friend can change the signal and power lines to be either 3.3V or 5V. Arduino-derivatives and XBees use the RTS line for programming but what if you need that DTR line? It's there for you.
The 6th pin is RTS (as of Arduino IDE v18 this will work perfectly for uploading to 'inos), the power wire is +5V and the signal levels are 3.3V (they are 5V compliant, and should work in the vast majority of 3.3V and 5V signal systems).

If you have a device that is running at 5V logic and requires 5V power, the FTID TTL-232 USB Cable may be better suited for your project needs.
