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 (Brown), TX (Tan-like/Peach), VCC (Red), and GND (Black). A link to the FTDI drivers can be found in the *Documents* section below.
