RPi HUB Module Datasheet Version 1.0 Document Reference No.: FT_000700 Clearance No.: FTDI# 297 Future Technology Devices International Ltd Datasheet RPi HUB Module Datasheet RPi HUB Module connects to a Raspberry-Pi computer and expands the number of interfaces that can be accessed downstream from a Host. RPi HUB Module also provides a dual channel USB UART/245FIFO/SPI/I2C/JTAG/GPIO interface converter. 1 Introduction The 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 twocolour (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 HiSpeed (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. FT2232H’s MPSSE interfaces are controlled over USB, for details on MPSSE see: Application Note AN_108. For more details on FT2232H see: FT2232H datasheet DS_FT2232H. 1.1 Ordering Information Product Name Order Code Description RPi HUB Module RPi-HUB-Module USB HUB and USB to dual channel multi interface converter module designed for Raspberry Pi.

Table 3.3 – RPi HUB Module Connection – J2 8 Copyright © 2012 Future Technology Devices International Limited RPi HUB Module Datasheet Version 1.0 Document Reference No.: FT_000700 Clearance No.: FTDI# 297 In most cases, the FT2232H pin is connected directly to the associated pin on J1 or J2. There are also several LEDs available on the FT2232H Hub-I/O to indicate the status of power and USB hub port. Detailed functions of LEDs are described in Table 3.4. LED Reference Colour Designator Function Description POWER Yellow Power active to downstream USB ports indicator PORT1 Red Overcurrent status of downstream USB port 1 indicator PORT1 Green Enumeration status of downstream USB port 1 indicator PORT2 Green Enumeration status of downstream USB port 2 indicator PORT2 Red Overcurrent status of downstream USB port 2 indicator Figure 3.4 – Functions of status LEDs on the module 4 Guide to Supplying Power When RPi HUB Module is connected to Raspberry Pi board it must be powered from external +5V power supply. The Raspberry Pi board can be powered by connecting P1-02 header to J2-24 on RPi HUB Module. To date, the Raspberry Pi uses a 140mA fuse on the power line to the USB connector; this fuse will not allow an adequate amount of current to power the RPi HUB Module from this USB connector. USB Bus powered configuration may be used with other host devices, such as PCs or laptops. To enable external power supply feature, switch the jumper JP1 and JP2 to SELF position, pins 2 & 3 shorted for both jumpers. The maximum total current consumed by the external USB devices on downstream port 1 and 2 is 1A. If the total current exceeds 1A, the fuse on the RPi HUB Module will disconnect the power to the USB downstream ports. If this occurs then LEDs PORT1 and PORT2 on the module will illuminate red to indicate over-current status. When powered from USB bus power, the estimated current consumed by the circuits on the module is between 100-300mA depending on the application. User should ensure that the host can supply this current via USB potation. 9 Copyright © 2012 Future Technology Devices International Limited RPi HUB Module Datasheet Version 1.0 Document Reference No.: FT_000700 5 Clearance No.: FTDI# 297 Mechanical Details 2.54 The mechanical details of the RPi HUB Module are shown in Figure 5.1: 16.21 3.77 CN2 13.07 GL850G 33.45 CN1 25.4 FT2232H 4.39 RPi Hub Module 12 5.88 2.15 CN3 8.89 JP1 JP2 1.22 14.71 12.55 65 15.8 5.3 10.8 4.82 1.7 Figure 5.1 – RPi HUB Module Dimensions diagram All dimensions are in millimetres.
