Athena III combines a full-featured wide temperature SBC with a professional quality data acquisition circuit, all on a compact board with PC/104 I/O expansion. This 2-in-1 design reduces the size and weight of your embedded system, while also helping to simplify manufacturing logistics such as purchasing, warehousing, and assembly. As a third generation product, Athena III demonstrates Diamond's support for long-lifecycle applications. It offers the latest processor and I/O technologies for new applications, while remaining backwards compatible with prior models to extend existing product lifetimes.

Athena III offers some of the highest feature density available in a compact SBC with rugged, wide-temperature, shock and vibration qualified operation. Its combination of size, weight, performance, and power consumption is an ideal fit for applications that require solid performance and a comprehensive range of I/O, without the burden of high cost or power consumption.

The Athena III SBC provides an ideal solution for applications requiring ruggedness.
Its many rugged features include:

  • Soldered memory for increased immunity to shock and vibration
  • -40ºC to +80ºC operating temperature fully tested
  • MIL-STD-202-G shock and vibration qualification (test report available)
  • Thicker PCB (.093" / 2.4mm) increases rigidity and enhances long-term reliability in high vibration environments
  • 2-in-1 SBC + data acquisition reduces size and weight and eliminates bus connectors and spacers for a more rugged solution
  • Athena III includes a complete set of standard I/O features:

  • 4 serial ports with RS-232/422/485 protocol support, configurable via BIOS
    (2 ports have 128-byte FIFOs and 460.8Kbps max data rate)
  • 4 USB 2.0 ports
  • Additional USB port for bolt-on solid state flash up to 8GB
  • SATA port for external mass storage
  • Parallel port for legacy applications
  • PS/2 keyboard / mouse ports
  • 1 Gigabit Ethernet port with 10/100/1000Mbps compatibility
  • VGA and LVDS LCD output with dual independent display capability
  • 24 digital I/O lines
  • top

    Integrated Data Acquisition

    Athena III includes a complete analog and digital data acquisition circuit integrated onto the board. The analog input circuit includes 16 single-ended / 8 differential channels with 16-bit resolution and programmable gain. The extremely high input impedance ensures accurate measurements, while the fault-protected input multiplexors provide protection from overvoltage conditions as well as live inputs during a power-off state. A 2048-sample FIFO with programmable threshold supports smooth interrupt-based sampling at any sample rate up to 200KHz.

    The circuit also features 4 12-bit analog voltage outputs with programmable output ranges, 24 digital I/O lines with programmable direction, and 2 counter/timers which can be used for A/D timing, timer-driven interrupts, or general counting functions.

    All data acquisition features are supported by our free, best-in-class Universal Driver 7.0 programming software which simplifies application development.

    Athena III Development Kit

    Diamond Systems offers the Athena III SBC in a development kit including a full set of accessories plus your choice of Windows 7 or Linux operating system, ready to run on an 8GB solid state flashdisk. Simply plug in the flashdisk, attach the included cables, add your keyboard, mouse, and display, and you're ready to boot into a fully functional OS. Configuration files and instructions are provided to rebuild the OS with your application. The Linux kit includes all the tools needed to rebuild the OS. The Windows 7 kit includes a runtime license. Developer tools are required to rebuild the Windows 7 OS.

    Mass Storage

    Athena III offers two methods for mass storage. A SATA connector enables the use of popular solid state drives, which can be mounted directly on the PC/104 stack using Diamond's ACC-HDDMOUNT disk mounting accessory board. In addition the board supports solid state wide-temperature flashdisks based on rugged SLC technology in up to 8GB capacity. These flashdisks bolt directly onto the Athena III SBC and communicate over a dedicated USB 2.0 port. Click here to learn more about our USB flashdisks.

    Pandora Enclosure System

    pc104 enclosure

    Diamond's Pandora enclosure system is an excellent choice for packaging the Athena III SBC into a complete, compact, ready to run PC for industrial control, gateway, or general application use. It includes a panel I/O board which provides standard commercial I/O connectors for most of the I/O features (LCD not supported). The panel I/O board plugs directly on top of the Athena III SBC, eliminating cables and creating a rugged assembly. The entire board set then mounts directly and easily to the front panel.

    Various case lengths are available to accommodate additional PC/104 I/O boards or custom electronics. The panel I/O board even includes extra I/O connectors to allow you to bring additional I/O out of the box without having to do any custom design. An optional DIN rail bracket helps simplify installation in many industrial applications.

    Pandora cases and panel I/O boards can also be customized for higher volume applications. Click here to learn more about the Pandora enclosure for Athena III.
