MEN Mikro SC27 - Intel® Atom™ SBC for Intelligent Displays

1.6 GHz E680T Processor, -40 to +70/85°C Operating


The SC27 is a rugged, fanless and maintenance-free single-board computer for rugged display computers, e.g., for in-seat infotainment purposes in trains, public buses or airplanes. Its small size makes it suitable for display devices with TFT LCD panels as small as 7".

The SC27 is controlled by an Intel® Atom™ E6xx processor running at 1.6 GHz and comes with 2 GB of DDR2 SDRAM and a MicroSD card slot. The standard interfaces comprise one Fast Ethernet (via M12 connector), two USB ports as well as a GNSS and RS232 or RS422/485 interface. Further I/O can be added via SA-Adapters. A temperature sensor is provided to monitor and control the display. The board's microSIM card slot and the microSD™ card slot can be made accessible on the display computer.

The SC27 is equipped with an internal 10 to 50.4 V (24 VDC nom. or 36 VDC nom.) wide-range power supply and able to operate in a -40 to +85°C environment with sufficient cooling. Optionally the SC27 can be supplied by a Power over Ethernet source with a power range of 37 to 57 V (48 VDC nom.). The SC27 provides EN 50155 conformity, which makes it ideal for any kind of railway application. All electronic components are soldered to withstand shock and vibration and are prepared for conformal coating.

Options include other types of the Intel® Atom™ E6xx series and a UART or CAN bus interface via an SA-Adapter. A PCI Express® Mini Card slot (with a microSIM card slot) in combination with an external antenna can be used to incorporate wireless functions like Wi-Fi, WIMAX, GSM/GPRS, UMTS, HSDPA and LTE.
