The product is equipped with an Intel Atom E3950 with 1,6 GHz, and offers CPU performance scalability by a variety of other dual/quad-core processors from the Intel Atom E3900 series. With 8 GiB of DDR3 SDRAM memory, a backward-accessible SD card and a Sata HDD/SSD shuttle, as well as an integrated eMMC memory, the box PC has the necessary storage capacity, e.g. for entertainment servers or video surveillance systems.

A CAN interface, two display port interfaces with a maximum resolution of 4K, four Gigabit Ethernet, two of them with PoE (Power over Ethernet) support, two USB 2.0 ports, and a serial I/O port complete the I/O functions.

The box PC is typically used in the transportation sector, such as trains, buses, or commercial vehicles, and can be used to provide wireless on-board functions like an internet connection for passengers, or to localize the vehicle. A variety of I/O functions and options connect the BL51E to the IoT. The application provides four PCI Express mini-card slots with two micro SIM slots and dual SIM support. This provides flexibility for implementing mobile service standards with up to 4G LTE or WLAN. There is also a GNSS interface for GPS or Glonass.

The complete system is designed for fanless operation in a temperature ranges of -40 °C to +85 °C. Due to the integrated 30 W/24 VDC power supply unit, the box PC complies with railway standard EN 50155 and with ISO 7637-2.
