Rugged, Sealed, and Compact Intel® Atom-Based Fanless Embedded Box PC

The XPand6903 provides a reliable and maintenance-free, cost-effective, computing platform ideally suited for environmentally challenging and space-constrained situations.

The XPand6903 supports the Intel® Atom™ E3800 family processor, which offers up to four cores at 1.91 GHz. The internal SATA SSD memory modules combine the convenience of high-capacity off-the-shelf storage with the reliability of solid-state non-volatile memory. The standard configuration includes dual VGA video, two Gigabit Ethernet ports, four USB ports, and RS-232/422 ports.

Fully rugged, the XPand6903 can operate under demanding shock and vibration requirements, as well as the water-immersion requirements of IP67, due to its environmentally sealed design. The XPand6903 also supports operating temperatures from -40°C to +70°C ambient.
