The TTL-232R-Rpi from FTDI is a USB to TTL level serial UART converter cable designed for use with a Raspberry Pi. Upon inspection, there is a USB connector with USB 2.0 full speed compatibility and 3 single pole 0.1m pitch header that connects to a serial port on the Raspberry Pi board. The cable is configured electrically to process and drive +3.3 V logic level UART signals.

What is the purpose of the cable?

This cable provides a simple method to analyse and debug your Raspberry Pi programming. The cable is connected to the Raspberry Pi ARM processor UART receive/transmit and provides detailed information from the Linux kernel to your PC.
