• 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 an older-version Raspberry Pi.
• The FTDI cable is designed around an FT232, which is ho d 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(5V)(Red), and GND(Black). A link to the FTDI drivers can be found in the
