TTL-232R-RPi Version 1.0 Document Reference No.: FT 000722 Clearance No.: FTDI 296 Future Technology Devices International Ltd Datasheet TTL-232R-RPi Debug Cable for Raspberry Pi Datasheet 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 FTDIs 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 whats 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. 1.1 Features 5V safe TTL inputs make the TTL-232R easy to TTL-232R-RPi Debug cable provides a USB to interface to 5V MCUs. TTL Serial interface for Raspberry Pi computer. FTDIs royalty-free VCP allow for communication On board FT232RQ provides single chip USB to as a standard emulated COM port and D2XX asynchronous serial data transfer interface. direct drivers provide DLL application Entire USB protocol handled by the electronics programming interface. in the cable USB.
