Rhodeus is a fan-less PC/104 SBC which features the AMD Geode LX800 low power consumption processor running at 500MHz. It uses high speed DDR SDRAM providing maximum capacity at 1GB. Rhodeus offers fully integrated PC functionality with low power consumption which allows Rhodeus to operate in harsh environments where the airflow for heat dissipation is restricted and heat sinks or fans are unacceptable. Its ruggedability gives it the power to perform round-the-clock in unattended environments.

Other advantages of Rhodeus includes high speed 10/100 Ethernet LAN and ample I/O interfaces, 2 serial ports, 2 USB 2.0 ports, parallel port for peripheral connection, 1 ATA-33 channel, Compact Flash Type-II socket, PC/104 expansion bus, LCD & CRT interface, floppy, and watchdog timer. Rhodeus has all the necessary features and expansion capability in 96 X 90 mm form factor, which makes it ideal for applications where space is limited but multiple I/O configurations are needed. Rhodeus supports Windows 2000, Windows XP, Windows CE 5.0, and Linux.

Development Kit

A Linux software development kit is available for Rhodeus. The Rhodeus Linux Kit (SDK-RDS-LNX) contains a 512MB CompactFlash disk with a bootable linux image pre-loaded, a software CD with the linux tool chain and a backup image, and documentation.

Pandora and Panel I/O Board

pc104 enclosure

Rhodeus single board computers can be mounted inside Diamond's Pandora PC/104 enclosure with a cable-free panel I/O board to form a rugged, compact, completely self-contained industrial computer system. The Pandora enclosure, coupled with the panel I/O board, features fast and easy assembly because most or all internal cables can be eliminated. Rather than requiring the installation of special corner mounts or forcing the stack into a set of corner guides, the entire stack is bolted directly to the front plate of the case, forming a rugged, easily-handled assembly.

Transition Cables or PC-Style Connectors

All I/O on Rhodeus is made available on 2mm pitch pin headers for use with low-cost cables. To enhance the use of Rhodeus in harsh environments requiring outstanding resistance to shock and vibration, Diamond Systems offers our rugged Pandora PC/104 enclosure that provides a cable-free configuration via a small panel I/O board that installs directly on top of the Rhodeus SBC to instantly convert all I/O to PC-style connectors.
