The BL70S is a fanless, maintenance-free box computer that has been designed for embedded storage applications such as content servers or video recorders. It offers two external SATA shuttles with hot-plugging support.

On the front of the rugged BL70S as many as five Gigabit Ethernet interfaces are accessible. Four of these ports share one Gigabit Ethernet port from the chipset via a switch, while one port is used exclusively as Gigabit Ethernet uplink. The four ports routed over the switch support Power-over-Ethernet.

One PCI Express® Mini Card slot with two SIM card slots offers the possibility to implement the wide range of functionality available on this form factor. This includes for example mobile service standards GSM (2G), UMTS (3G), LTE (4G) and derivates, wireless communication standards WLAN / Wi-Fi IEEE 802.11 and derivates as well as positioning systems GPS or GLONASS.

The BL70S is powered by an Intel® Core™ i7-3517UE CPU, running at 1.7 GHz. Other processors of the 3rd generation Intel® Core™ i7 family can be used which makes for high scalability in CPU (single/dual/quad core) performance.

The BL70S is equipped with 4 GB of DDR3 SDRAM and offers microSD™ card and mSATA slots. The system is designed for fanless operation at temperatures from -40 to +70°C (+85°C for up to 10 minutes), its special aluminum housing with cooling fins serves as a heat sink for the internal electronics and in this way provides conduction cooling.

The BL70S supports one DisplayPort® interface with a resolution of 2560x1600. In addition, a multitude of other I/O is available at the front panel, including two USB 2.0 and variable slots for legacy serial I/O (e.g. RS232) or CAN bus.

The BL70S comes with its own integrated class S2 wide-range power supply with 24 and 36 VDC nominal input voltage (10 to 50.4 V) and a power consumption of 30 W and is in compliance with EN 50155 and ISO 7637-2 (E-mark for automotive). The power can be switched on and off using an ignition signal on the power connector, and a run-down time after switching off the power can be adjusted by software.

The various CPU options with the available selection of external interfaces makes for an extremely flexible system design that can quickly be tailored to a vast number of applications.
