Description: This is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins, this cable is a perfect candidate for powering, connecting, and accessing the login and debug console on the Raspberry Pi.
The FTDI cable is designed around an FT232, which is housed in a USB-A connector. The other side of the cable is terminated with a separated 4-pin connector with the following pinout: RX (Yellow), TX (Orange), VCC (Red), and GND (Black). A link to the FTDI drivers can be found in the Documents section below.
Note: Please be aware that while the I/O pins in this cable operate at 3.3V, the VCC pin is 5V. The VCC pin is NOT 3.3V like the I/O pins.

This product works well, but I thought it was regulating the USB 5V down to 3.3V. I realize now that I didn’t read closely enough.
And here’s why …
needed an out-of-the-box solution for communicating with the UART on an Atmel XMEGA eval board.
This thing was plug in and go.
no fuss, no muss.
I bought this to connect to my Raspberry Pi console. After a little experimentation, it worked fine (connect Tx to Rx; not Tx to Tx).
I found it reliable and easy to connect.
This cable is a great price and great value. I used it to build a usb programming cradle for fire dept Motorola minitor 3 and 4 pagers. Works flawlessly after updating the drivers from the product page. The shipping was fast and packing was super.
What else can I say?
Performs right out of the box, good driver support from the manufacturer!
