“Extreme rugged” Mini-ITX SBC runs Linux on Bay Trail

Nov 12, 2015 — by Bill Traynor — 1,360 views

Adlink’s Mini-ITX-BT-I SBC runs Linux on Intel Bay Trail SoCs, and offers 8GB RAM, dual GbE, and rich multimedia, plus MIL spec shake-and-bake ruggedness.

Adlink says its “AmITX-BT-I” single board computer targets applications that demand high-level processing and graphics performance, along with low power consumption. The “Extreme Rugged” board joins an assortment of competing Bay Trail-based Mini-ITX SBCs including Habey’s MITX-6771 and MITX-6770, Aaeon’s EMB-BTx series, Axiomtek’s MANO842, DFI’s BT160, and Portwell’s WADE-8078. Adlink’s board appears to be unique among the pack in its MIL spec-level shock and vibration resistance (see table farther below), and support for -40 to 85°C operating environments. Presumably, meeting these specs requires the use of carefully designed thermal management solutions.

The AmITX-BT-I can be ordered with any of Intel’s Atom E3800 series (Bay Trail) or related Intel Celeron N2930 or J1900 system-on-chips. The board’s dual-stacked SODIMM sockets accommodate up to 8GB of non-ECC DDR3L RAM, and there’s also an option for 8GB to 64GB of on-board eMMC storage.

The board’s Bay Trail SoCs integrate Intel’s Generation7 HD Graphics, which offer compatibility with OpenGL 3.1, DirectX 11, OpenCL 1.1 standards and support for H.264, MPEG2, VC1, and VP8 hardware decode. Available display outputs include analog VGA, HDMI, and optional dual-channel 18/24-bit LVDS, with support for dual-independent, simultaneous display operation.

Other interfaces include a pair of Gigabit Ethernet ports, three helpings each of USB 3.0 and 2.0 ports, a pair of SATA 3Gb/s interfaces with one routing to an mSATA slot, analog and S/PDIF audio I/O, six serial ports, GPIO, and a PS2 port. The board’s PCIe expansion includes a PCIe x1 card slot along with a full-sized mini-PCIe slot with USB 2.0 and SIM card support.
