RevPi Connect+

KU-PR100302 , KU-PR100304

Product is no longer available.

These units are EOL, and the recommended replacements can be found here.

The RevPi Connect+ from KUNBUS is an open source Industrial IoT (IIoT) gateway giving users the ultimate in flexibility. RevPi Connect+ is based on the Raspberry Pi Compute Module 3 (CM3B+), and features a 1.2 GHz quad-core processor, 1 GB RAM and 8 GB (up to 32 GB) eMMC flash memory. The operating system is a customized Raspbian version with a real time patch. Common IIoT protocols such as OPC UA and MQTT are fully supported allowing the transfer of data directly to the cloud.

Individual applications may be programmed using Node-RED, Python, or C programming. The modular design allows the 45mm base device to be fitted with expansion modules such as digital and analog I/Os, fieldbus gateways and radio modules including Bluetooth. The expansion modules may be connected with the base device via a socket located at the top, and is easily configured with an intuitive GUI.
