The KBox A-250 is tailored for gateway applications. Based on a pITX-2.5“ SBC with Intel Atom® processors of the E3900 family, the fanless KBox A-250 has been designed as a cost-optimized gateway for IoT-Edge applications. Its fields of application are primarily found in industrial automation.

The compact KBox A-250 offers numerous interfaces to connect various layers of communication: a serial interface (RS232) for local data collection, and connection to the sensor- or machine environment. Connection to the IT environment can be realized through the integrated Gigabit Ethernet interfaces as well optional Wifi support. Additionally, a GPIO-interface is included. Wireless technologies such as LTE (4G) and GSM (2G/3G) are supported, an integrated LTE module can be added on demand.

As a partner for industrial hardware and software, we offer system solutions such as the Connect IoT Bundle, consisting of our high-performance KBox A-250 box PC and the FabEagle®Connect integration software for industrial interfaces. This allows you to obtain hardware with pre-installed software ex works to reliably equip small to large series of machines with modern, industrial-grade IoT gateways.

To meet the increased cyber security requirements, Kontron offers the hardened and secure Linux®-based KontronOS operating system and the KontronGrid fleet management solution for managing and simplifying the roll-out of container applications on edge devices.
