Diamond Systems Poseidon is a high performance EPIC form factor single board computer combining state of the art CPU and peripheral technology with Diamond Systems renown high accuracy data acquisition circuitry on a single board. Poseidon utilizes the VIA C7® and VIA Eden® ULV based on the C5J “Esther” core, operating at speeds up to 2.0GHz. The 1.0GHz VIA Eden ULV version of Poseidon operates fanless over the extended operating temperature range of -20°C to +85°C. The 2.0GHz VIA C7 version of Poseidon operates with a fan from -20°C to +65°C.

Poseidon incorporates VIA’s advanced CX700 single chip digital media chipset, providing advanced features such as a 400MHz Front Side Bus (FSB), four USB 2.0 ports, S-ATA hard drive interface and advanced VIA UniChrome™ Pro 2D / 3D graphics with AGP 8x level performance and integral MPEG-2 hardware acceleration. The dual graphics display engines on Poseidon support Dual Independent Display functionality with simultaneous CRT and LVDS flat panel displays (up to dual channel 24-bit) which can display different images with different pixelization and different resolutions.

Like other Diamond Systems SBCs, Poseidon features soldered DRAM for increased resistance to shock and vibration. Poseidon provides either 512MB of DDR2 DRAM operating at 533MHz.

Poseidon also provides an Intel 82541 Gigabit Ethernet controller, four RS-232 serial ports (two have RS422/485 multiprotocol capability) and legacy keyboard / mouse and IDE hard drive interfaces.
