Linux-friendly SBC suits display apps on trains, planes, buses

May 22, 2013 — by Rick Lehrbaum — 698 views

MEN Mikro announced a compact, rugged single-board computer based on Intel’s 1.6GHz Atom E600-series embedded processors. The Linux-friendly SC27 SBC is aimed at driver displays and in-seat infotainment systems in trains, buses, and airplanes, where wide-temperature operation and resistance to shock, vibration, and dust are critical.

The SC27’s compact size (6.3 x 4.3 inches) makes it well matched for use with TFT LCD panels as small as 7-inches, says Men Mikro. The board works with up to 15-inch displays, and supports resolutions as high as 1280 x 678 pixels. It consumes 5 to 7 Watts, operates over an extended temperature range of -40 to +85° C, and was designed for ease of conformal coating.

The SC27 is based on a choice of Intel Atom E600-series processors, clocked up to 1.6GHz, and accommodates up to 2GB soldered-on SDRAM. Standard onboard I/O includes 10/100Mbps Ethernet, two USB ports, an RS232 or RS422/485 serial port, and a built-in GPS receiver.

The SC27 includes a range of expansion interfaces, including slots for mSATA, microSD, microSIM cards, and PCIe MiniCards. It also has two locations for optional addition of MEN Mikro’s proprietary-format SA-Adapter modules, which support functions such as additional UARTs or a CAN bus interface. In particular, the board’s PCIe MiniCard socket accommodates add-ons for WIFI, WIMAX, GSM/GPRS, UMTS, HSDPA, and LTE, and is paired with a microSIM card slot for use with cellular network modules.
