The TTL-232R-RPi cable provides USB to TTL Level UART solutions and
is customised for operation with the Raspberry Pi.
1 Introduction
TTL-232R-RPi is a USB to TTL level serial UART converter cables incorporating FTDI’s FT232RQ USB to
Serial UART interface IC device which handles all the USB signalling and protocols. The TTL-232R-RPi is
designed for use with the Raspberry Pi (RPi), an ultra-low cost, Linux based miniaturised computer. The
debug cable sits on the Rx/Tx of the RPi ARM processor UART – which provides much more detail of
what’s happening within the RPi operating system. Connecting the debug cable to a PC and
communicating with the RPi via a terminal emulator on a PC gives the user access to more detailed
information from the Linux kernel during RPi start-up, which appears on the Rx/TX lines of the UART, as
well as being able to login and access the kernel itself from the PC.
