Altair is a high performance, highly integrated small form factor single board computer in the COM Express form factor. Altair incorporates a wealth of standard PC-style I/O plus on-board digital I/O. It accepts both EMX and PCIe MiniCard add-on I/O modules.

The SBC supports either 1GB or 2GB of DDR2 DRAM soldered on-board and provides high-resolution LVDS and VGA graphics interfaces. Additional I/O ports include SATA, USB, serial, CAN, digital I/O, and Gigabit Ethernet. Flexible system expansion is based on stackable EMX I/O modules, and a PCIe MiniCard socket. A socket is also provided for an optional on-board USB flashdisk of up to 8GB.

Altair features an on-board PIC microcontroller that adds an extra 895 bytes of user EEPROM data storage along with additional I/O including 4 single-ended A/D inputs, 10 programmable digital I/O, 4 PWM outputs, 2 counter/timers, a software configurable watchdog timer, and a real-time clock with calendar feature.

Altair's power-efficient design leverages Intel's ultra-low-power (Queensbay) silicon platform, consisting of the Atom E680T (Tunnel Creek) processor and EG20T chipset (Topcliff). These ICs are positioned on the bottom of the board, resulting in easy and efficient heat removal via a heatspreader for wide temperature, fanless operation. Altair utilizes conduction cooling for improved ruggedness and reliability through the use of a heatspreader mounted on its bottom side, resulting in optimal thermal management and increased space for I/O functions and connectors. The four mounting holes on the bottom of the conduction cooled heatspreader are #6-32 threaded holes on 2.8" centers.

The SBC's Intel Atom E-Series CPU offers an excellent balance of performance, power consumption, and cost, making Altair an ideal choice for a wide variety of high-performance embedded computing applications. Altair is also virtualization ready, enabled by physical address extension (PAE).

Altair was designed to meet the needs of real-world applications. The SBC integrates an optimal selection of features for its size, power, and cost budgets, yielding maximum functionality and performance within a compact board. Latest generation connectivity such as SATA, Gigabit Ethernet, and PCI Express ensures long lifetime and top performance. EMX and PCIe MiniCard expandability provides access to current and future high-speed I/O.

Software Support

Altair runs Linux, Windows Embedded Standard 7, and Windows Embedded CE. All OS drivers are shipped with the product.

The EMX Standard


EmbeddedXpress (EMX) is a new generation, highly efficient embedded form factor designed to provide an efficient solution for PCI Express I/O expansion in a rugged, low-cost, small format. EMX is optimized for use with COM Express and QSeven based systems and is an ideal choice for providing I/O expansion in off the shelf and custom embedded systems using these and other COMs. EMX also works with single board computers in the EMX Basic and Compact form factors.
