RevPi Flat

by Kunbus GmbH

The open source platform for the energy industry

The energy industry today faces enormous challenges. Renewable energies, electromobility and grid expansion are just some of the buzzwords being discussed in politics, the media and society. In addition, the liberalisation of the electricity market and the resulting increase in competition as well as digitalisation allow completely new structures and business models.

The associated complex requirements and tasks can be realized by using the RevPi Flat. This module based on Raspberry Pi convinces with its genuine industrial suitability and a large number of interfaces. Thanks to the open platform concept (including full root rights), the device guarantees maximum design freedom when implementing your projects.

Tamper protection is important in the energy industry. Therefore, the RevPi Flat is equipped with a Trusted Platform Module (TPM). Furthermore, Kunbus have deliberately omitted a micro-USB socket for uploading a new software image with this device.
