FTDI Raspberry Pi Interface and Debug Modules

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.

Features
  • TTL-232R-RPi Debug cable provides a USB to TTL Serial interface for Raspberry Pi computer.
  • On board FT232RQ provides single chip USB to asynchronous serial data transfer interface.
  • Entire USB protocol handled by the electronics in the cable USB.
  • Connect directly to a microcontroller UART or I/O pins.
  • UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd/even/mark/space/no parity.
  • Fully assisted or X-On/X-Off software handshaking.
  • Data transfer rates from 300 baud to 3 Mbaud at TTL levels.
  • Internal EEPROM with user writeable area.
  • 5V safe TTL inputs make the TTL-232R easy to interface to 5V MCU’s.
  • FTDI’s royalty-free VCP allow for communication as a standard emulated COM port and D2XX ‘direct’ drivers provide DLL application programming interface.
  • Support for FT232R FTDIChip-ID™ feature for improved security.
  • 3x ‘flying leads’ outputs provide TXD, RXD and GND signals.
  • Low USB bandwidth consumption.
  • UHCI / OHCI / EHCI host controller compatible.
  • USB 2.0 Full Speed compatible.
  • -40°C to +85°C operating temperature range.
  • Cable length is 1.0m.
  • FCC and CE compliant.

FTDI Raspberry Pi Interface and Debug Modules

FTDI FT2232H based RPi HUB Module is a USB to UART/245FIFO/SPI/I2C/JTAG/GPIO interface expansion module targeted at connecting to Raspberry-Pi computer to expand the number of interfaces. However, it is not limited to this application. It can also be used as a hub device or an FT2232H evaluation module. The module has a USB 2.0 Hi-Speed hub chip which supports up to three external downstream USB ports: 2 via a dual USB connector and 1 via the DIL connector pins .Additionally, by utilising the FT2232H USB Hi-Speed dual-port bridge chip which handles all the USB signalling and protocols, the module can easily support up to two flexible interfacing ports. It is ideal for development purposes to quickly prove functionality of adding USB to a target design. This module utilises the GL850G USB 2.0 hub controller which provides a low-cost and widely used USB 2.0 hub solution, to provide up to 4 downstream USB ports. The GL850G is a single chip USB hub solution. The GL850G is a full function solution which supports both Individual/Gang power management modes and two-color (green/amber) status LED. The FT2232H used on the Module is FTDI’s 5th generation of USB devices. The FT2232H is a USB 2.0 Hi-Speed (480Mb/s) to UART/MPSSE IC. The device features two interfaces that can be configured for asynchronous or synchronous serial communications or Parallel FIFO Interface. The two interfaces can also be independently configured via an MPSSE engine .This allows the FT2232H to operate as two UART/Bit-Bang ports or two MPSSE engines which can be used to emulate JTAG, SPI, I2C, Bit-bang or other synchronous serial modes. All I/Os of the RPi HUB Module operate at 3.3V TTL and are 5V safe.
