Kontron KBox A-250

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/RS485) 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.
