Contec's BX-320 is a small, fanless PC for embedding with a palm-size body that can be mounted on a 35mm DIN rail. The product features the quad-core Intel Atom E3845 Atom CPU and supports up to 4GB of DDR3 DRAM (via SODIMM). Standard interfaces include dual GbE interfaces (with WOL support), audio (line out and mic in), one USB 3.0 port, three USB 2.0 ports, two standard RS-232C ports, VGA graphics and GPIO. Storage is realised through two CFast sockets (one removable. CFast is a SATA-based storage card and is available in capacities from 2GB to 256GB.

This product is the successor to the previous BX-300 microcontroller products and it meets the needs of replacing the BX-300 in systems. 

The functionality of this product can also be expanded in ways such as adding analogue, digital and serial I/O by connecting F&eIT Series device modules. Additionally, this product is equipped with an external expansion connector that can be connected by cable to an expansion chassis for PCI/PCI Express expansion boards.
