FTDI FT232RL TTL-232R-RPI USB to UART 3.3V TTL Logic Level Cable, Raspberry Pi Compatible Flying Leads Serial Adapter Cable
Part No: TTL-232R-RPI
USB to UART, 3.3V TTL logic level, Raspberry Pi compatible flying leads
USB to asynchronous serial data cable with +3.3V TTL level UART signals
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.

The TTL-232R-RPi debug cables require USB drivers, available free from http://www.ftdichip.com, which
are used to make the FT232R in the cable appear as a virtual COM port (VCP). This then allows the user
to communicate with the USB interface via a standard PC serial emulation port (for example TTY).
Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access
the FT232R on the cable though a DLL. This is illustrated in the Figure
TTL-232R-RPi is a USB-to-TTL Serial UART debug cable. It is designed to be used with the Raspberry Pi
(RPi) Linux-based computer. This cable provides a fast, simple way for a PC to interface with an RPi, to
carry out program analysis and debugging.
This cable is electrically configured to process and drive +3.3 V logic level UART signals. The USB side of
the cable is USB powered and USB 2.0 Full Speed compatible, supporting data transfer rates up to 3
Mbaud. Spanning 1.0m in length, the TTL-232R-RPi debug cable connects directly to the serial port on
the RPi board. The RPi’s serial port can output kernel debug messages even if it has not been completely
booted.
The following serial communication parameters should be used to access the serial/debugger port on
Raspberry Pi board:
* Speed: 115200 baud
* Bits: 8
* Parity: None
* Stop Bits: 1
* Flow Control: None

TTL-232R-RPi Debug cable connection diagram
The TTL-232R-RPi Debug cable should be connected to Raspberry Pi board according to the diagram
below.
Please note that TXD-orange wire should be connected to RX pin on RPi board and RXD-yellow wire
should be connected to TX pin on RPi board.
The Photo just for reference, actual product should be 6FT/1.8m in Length
