The RevPi Compact is an open source compact control system based on the Raspberry Pi 3+ Compute Module.

The open platform concept (including full root rights) allows the user maximum design freedom in the implementation of his projects.

To connect sensors and actuators, the RevPi Compact is equipped with eight digital and analog inputs each as well as eight digital and two analog outputs. In addition, the device has also a 4-pole RS485 interface with screw terminals. Two Ethernet interfaces (each with a separate MAC address) enable the device to be integrated in two different networks at the same time.

The flat design of the RevPi Compact makes it possible to install it in a subdistribution system that is usually found in building automation.

A customized Raspbian with Real-Time Patch is used as operating system. Individual applications can be programmed via, amongst other things, Node-RED, Python or directly in C. The popular industrial protocols Modbus RTU and Modbus TCP are supported by default.

Those who do not want to program by themselves can optionally use professional soft PLC and SCADA software for control and visualization.

Interfaces

  • 2 x RJ45 10/100 Ethernet (using separate MAC addresses)
