Raspberry Pi Based Controller With CAN Bus Interface Serves As IoT Gateway
Kontron (Germany) has released its series of KBox A-330-MX6 host controllers, which can also serve as IoT (Internet-of-Things) gateways. The KBox A-330-MX6 is based on the Raspberry Pi Compute Module CM3+ and can, therefore, use the software pool of the Raspberry Pi community. The host controller with IoT gateway functionality comes with an i.MX6 dual-core processor from NXP Broadcom. Optionally, the processor can run a CANopen protocol stack.
Both products operate without a fan and are suitable for industrial control and gateway tasks in control cabinets due to their slim design and the possibility of DIN-rail mounting. Besides a CAN Bus interface, there are two Fast-Ethernet connections, serial links (EIA-232 and EIA-485) as well as four I/O ports. A user interface can operate during commissioning or in the target application via two USB channels and an HDMI connection.
With this device, Kontron offers an industrial-grade platform. It can serve as a gateway for IoT applications and can integrate sensors and actuators via CANopen. The company also provides CANopen I/O modules with up to 16 galvanic-isolated digital inputs and up to 16 galvanic-isolated digital outputs. Further options include two quad-decoder, two counter inputs, four analog inputs, four analog outputs, and four RTD inputs, and these I/O devices can be configured according to application requirements.
As operating system Yocto Linux is available. On a project basis, applications are possible to include advanced security features such as secure authentication and data encryption. In combination with the modular Susietec IoT software framework from Kontron's sister company, S&T Technologies, cloud solutions are available to support the development of IoT applications.
