The compact industrial computing platform KBox A-203 is perfectly suited for gateway applications. Based on the latest Intel Atom® E3900 line processors, the low-maintenance, fanless and battery-free Kontron KBox A-203 serves an intelligent gateway for data-intensive IoT edge applications. Areas of use include the industrial automation sector in particular as well as the transportation and communications field.

The Kontron KBox A-203 can be deployed quickly and efficiently. This makes it the perfect fit for OEM manufacturers and system integrators aiming to utilize the full potential of next-generation intelligent infrastructures in an IoT context. The KBox A-203 is Microsoft Azure Certified, which makes it perfectly suited for working with Microsoft Azure IoT services.

The KBox A-203, based on the SMARC 2.0 standard, offers numerous interfaces allowing for the connection of various communication layers. Two RS232/RS485 serial interfaces are provided for local data collection or linking up to the sensor- or machine environment. Optionally, fieldbuses such as Profibus are supported as well. The connection to the IT infrastructure, in general, can be implemented through integrated gigabit Ethernet interfaces or optional WiFi support. Project-based integration of wireless technologies such as LTE (4G) and GSM (2G/3G) is a further option.
