KUNBUS are the specialists in industrial automation and IIoT and the company behind the open source hardware platform Revolution Pi, a modular & industrial-grade device series based on the Raspberry Pi.

In 2016, KUNBUS introduced Revolution Pi, the first open source industrial PC based on the Raspberry Pi Compute Module. The Compute Module is Raspberry Pi in a more flexible form factor, and is intended for industrial application. From the outset, the mission was to develop a low-cost, scalable and industrially suitable controller and to consistently continue the basic idea of Raspberry Pi. Thus, we make no secret of the hardware, source codes and software. Even more, we consciously carry the open source idea internally and externally. We share knowledge, feedback and new approaches from our community and set a new standard in the environment of Industry 4.0. In fact, the success of the Revolution Pi shows that the risk of bringing an open source product to the automation market has been worth it.
