FTDI Cable 5V

by Sparkfun

The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this FTDI cable are configured to operate at 5V.

The FTDI cable is designed around an FT232RQ, which is housed in a USB A connector. The other side of the cable is terminated with a 0.1" pitch, 6-pin connector with the following pinout: RTS, RX, TX, 5V, CTS, GND (RTS is the green cable and GND is black).

This cable has the same pinout and functionality as our FTDI Basic Breakout board; you can use it to program your Arduino Pro, Pro Miniย and Lilypad. For use with those boards, align the black and green wires of the FTDI cable with the โ€˜BLKโ€™ and โ€˜GRNโ€™ labels on the PCB.

There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators, but 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.
