The company presents its product at the Innotrans 2018 exhibition in Berlin, Germany. The fair takes place from 18 September to 21 September.

The product is based on AMD's Ryzen V1000 APU family featuring power-per-watt performance and a Radeon Vega 3D graphics engine. With up to four processor cores and AMD virtualization support, and up to 32 GiB soldered-down DDR4 SDRAM, the BL72E offers computing for handling data intensive work loads.

To provide Internet connection for passengers or locating the vehicle, many wireless options are available. This includes a GNSS positioning interface, two PCI Express Mini Card slots and two M.2 slots for implementing mobile service standards up to 4G LTE or WLAN IEEE 802.11, and derivates.

The product supports one Displayport interface with maximum 4K resolution. It also features two CAN ports. A multitude of other I/O is available, including four Gigabit Ethernet, audio, two USB 3.0, EIA-232, EIA-422/EIA-485, IBIS, digital inputs and outputs. An MVB master or slave interface can optionally be implemented.

A total of eight externally accessible micro-SIM card slots are available as well. The box can be delivered with a second I/O board offering additional LTE modems, storage, and I/O.

The device offers a Sata HDD/SSD shuttle providing the storage capacity necessary for entertainment servers or video surveillance systems, plus eMMC memory and an M.2 slot for PCIe based storage (NVMe).

It comes with a class S2 wide range power supply and complies to EN 50155. Its rugged aluminum housing with cooling fins serves as a heat sink and provides conduction cooling. This allows fanless operation at temperatures from -40 °C to +70 °C.
