Meet Revolution Pi: A Raspberry Pi-Based Industrial Mini PC


You must have heard of the credit card size, in-expensive single-board computer, Raspberry Pi, that has revolutionized the world of computing, programming, and electronics.

Similarly, to leverage the power of computing for businesses, KUNBUS develops an Industrial PC based on the Compute Module of Raspberry Pi to automate and implement the IIoT and manufacturing process in the period of fourth Industrial Revolutions.

What is Revolution Pi?

As quoted on the official site, Revolution Pi is an open, modular, and inexpensive industrial PC based on the well-known Raspberry Pi. It is composed of open hardware and software to meet the EN61131-2 standard.

The modular structure enables base modules to expand seamlessly via a variety of suitable I/O modules and Fieldbus gateways.

KUNBUS, a company developing the RevPi PCs, aims to provide open source tools to the companies and enable them to build business models and services.

KUNBUS follows the Open Source concept to strengthen community development and bring more ideas. Hence, it promises to reveal the source code and all the circuit diagrams of the Revolution Pi devices.

Revolution Pi Modules

RevPi modules are equipped with a Raspberry Pi Compute Module and Raspbian operating system. Most of the applications developed for the Raspberry Pi are compatible with Revolution Pi.

RevPi family comprises of two types of modules: Base and Expansion Module. Let’s have a brief look at each module:

Base Module

The base module is the foundational CPUs of RevPi family available in three variants, RevPi Connect, Core 3, and Core.

Revolution Pi Base modules: Core and Connect

Base module ships with the power supply circuit to efficiently handle heat dissipation. It can run on as little as 10.2V power voltage up to a maximum of 28.8V.

RevPi Core couples with common interfaces like RJ45 Ethernet connector, USB-A connector, Micro-HDMI, and Micro-USB plug. It also offers PiBridge to extend it further and connect with multiple RevPi expansion modules.

RevPi base module general specifications:

  • Processor: Broadcom BCM2835, BCM2837, BCM2837B0
  • No of cores: 1 to 4
  • RAM: 512MB to 1GB
  • eMMC flash memory: 4 to 32GB
  • Clock rate: 700MHz to 1.2GHz
  • Power supply: 12 to 24V

Expansion Module

The expansion module is the industrial control unit to integrate a device into the industrial network using special data transmission protocol.

Revolution Pi Expanded modules: Digital and Analog I/O, Gateways

Revolution Pi system can be expanded using the expansion module by connecting the analog sensors, actuators, and Fieldbus or Industrial Ethernet networks.

The expansion module is also available in three variants: Digital I/O, Analog I/O, and Gateways. It can be connected to the base module using the PiBridge connector.

If you want to buy RevPi, you can order online directly from the official website.
