Data Modul’s fanless, Pico-ITX “eDM-pITX-BT” SBC runs Linux on Intel’s Bay Trail SoCs, ranging from a single-core 1.5GHz Atom to a quad-core 2.4GHz Celeron.
Munich-based Data Modul says it developed the eDM-pITX-BT “in cooperation with a long-term partner, a leading manufacturer of industrial computers.” In addition to its passively-cooled, soldered Intel processor, the board features up to 4GB of DDR3L RAM, a CAN 2.0 interface, a pair of mini-PCIe expansion positions, and an assurance of seven-year product longevity.

Although fanless, the eDM-pITX-BT optionally supports an industrial temperature range of -40 to 85°C, which presumably requires a carefully designed thermal solution, especially when equipped with the 2.42GHz J1900 processor option. To aid the heat-extraction process, “heat sources like CPU and RAM are located at the rear side of the PCB,” and the company offers 15mm-thick heat spreaders and a heat sinks for mounting on the board’s bottom. “With the heat spreader the board can be directly adapted to a housing,” adds the company.

The board offers dual-display operation, and provides two display interface styles: a DisplayPort, supporting up to 2560 x 1600 pixel resolution, and dual 24-bit LVDS interfaces, usable with up to 1920 x 1200 pixel displays. Other I/O includes Intel HD Audio, four USB ports (including three USB 2.0 and one USB 3.0 SuperSpeed), a pair of serial ports with one supporting RS422/485, and a CAN 2.0 bus suitable for industrial applications.
A SATA 2.0 interface usable with external HDD or SSD media supports up to 3GB/s transfer rates, and there’s a Gigabit Ethernet port for high-speed networking. Additional, modular expansion is enabled by a pair of half-size mini-PCIe slots, one of which supports mSATA.

Although the eDM-pITX-BT is a late entrant in the small form-factor Bay Trail SBC market, the board’s robust specs and seven-year lifecycle certainly justify its existence. Other Bay Trail-based Pico-ITX SBCs we’ve seen include the Kontron pITX-E38, introduced last March, and the Commell LP-173, introduced in August. (Both are shown above.)
