The Industrial Raspberry Pi: From School to the Shop Floor
Eben Upton‘s vision was to create an affordable and accessible computer that would help students learn programming and develop their technological skills. The Raspberry Pi offers a variety of advantages and unique selling points, including a low price, broad community support, ease of use and high expandability. With its powerful software, such as the open-source Linux-based operating system Raspberry Pi OS (formerly called Raspbian), users can access a wealth of tools, libraries and projects developed specifically for the Raspberry Pi. This enables people to realize their own projects and express their creativity in the fields of electronics, programming and robotics.
The Raspberry Pi, or more precisely the Raspberry Pi Model B, has established itself as an extremely popular single-board computer. Nevertheless, it has some features that make it less suitable for use in industrial environments. Firstly, due to its form factor and size, the Raspberry Pi Model B is not ideally suited for installation in industrial housings or integration into existing industrial systems. In addition, it lacks specific functions and interfaces that may be required for industrial applications, such as extended I/O options, tolerances against interference or an improved power supply.
The Raspberry Pi Compute Module: The Game Changer for Use in Industry
To meet these challenges and better meet the requirements of industry, the Raspberry Pi Foundation developed the Raspberry Pi Compute Module in 2014. The Compute Module was specially designed for use in industrial and commercial environments. It has a compact form factor that enables easy integration into existing systems. The Compute Module requires a so-called carrier board in order to be used. The Compute Module itself is a slimmed-down version of the Raspberry Pi, which does not have any connections or interfaces such as USB ports, HDMI or Ethernet directly. Instead, the compute module is plugged onto a carrier board, which provides the necessary connections, interfaces and expansion options. The carrier board serves as an interface between the compute module and other components or devices, allowing the compute module to be integrated into various applications and systems. It extends the functionality of the compute module and offers additional flexibility and customization options.
Das Raspberry Pi Compute Module: Der Game-Changer für den Einsatz in der Industrie
Um diesen Herausforderungen gerecht zu werden und den Anforderungen der Industrie besser zu entsprechen, hat die Raspberry Pi Foundation im Jahr 2014 das Raspberry Pi Compute Module entwickelt. Das Compute Module wurde speziell für den Einsatz in industriellen und kommerziellen Umgebungen konzipiert. Es ist in einem kompakten Formfaktor gehalten, der eine einfache Integration in bestehende Systeme ermöglicht. Das Compute Module benötigt ein sogenanntes Carrier Board, um genutzt werden zu können. Das Compute Module selbst ist eine abgespeckte Version des Raspberry Pi, die keine Anschlüsse oder Schnittstellen wie USB-Ports, HDMI oder Ethernet direkt aufweist. Stattdessen wird das Compute Module auf ein Carrier Board gesteckt, das die erforderlichen Anschlüsse, Schnittstellen und Erweiterungsmöglichkeiten bereitstellt. Das Carrier Board dient als Schnittstelle zwischen dem Compute Module und anderen Komponenten oder Geräten und ermöglicht so die Integration des Compute Modules in verschiedene Anwendungen und Systeme. Es erweitert die Funktionalität des Compute Modules und bietet zusätzliche Flexibilität und Anpassungsmöglichkeiten.
2024
Raspberry Pi Compute Module 5
The Compute Module 5 was launched at the end of 2024. Thanks to an Arm Cortex-A76 with a clock speed of 2.4 GHz and LPDDR4X RAM, the fifth generation achieves a significant increase in performance compared to its predecessor.
2022
Raspberry Pi Compute Module 4S
In 2022, the Raspberry Pi Foundation decided to make a Compute Module 4S available to selected customers due to the global chip crisis triggered by the Covid-19 pandemic, among other things. This Compute Module 4S is characterised by the fact that it uses the same processor as the Compute Module 4 with the Cortex-A72 arm, but retains the familiar SODIMM design as the board form factor. This module therefore also has no WLAN and no PCIe interface. While the module was initially only available with 1 GB RAM, Raspberry Pi has also been offering the module with up to 8 GB RAM since 2024 and is now available to everyone. We use the Compute Module 4S (CM4S for short) in the Revolution Pi S/SE series, for example.
2020
Raspberry Pi Compute Module 4
The Compute Module 4 was introduced in 2020. The fourth generation of the Compute Module is the first to no longer use the familiar SODIMM form factor, but a new form factor similar in size to a credit card with a dual 100-pin electrical high-density interface connector. Compared to the Compute Module 3+, the Compute Module 4 offers a range of improvements and new features, including a more powerful processor with the Cortex-A72 arm, extended RAM capacity of up to 8 GB, optional availability of WLAN and Bluetooth, a PCIe interface and support for Gigabit Ethernet.
2019
Raspberry Pi Compute Module 3+
The Compute Module 3+ was introduced in 2019 and was a further development of the Compute Module 3. The biggest difference was that from now on, there was no longer just 4 GB of eMMC flash memory available, but a choice between 8 GB, 16 GB and 32 GB of eMMC flash memory.
2017
Raspberry Pi Compute Module 3
In 2017, the Compute Module 3 followed (there was never a Compute Module 2), which was based on the Raspberry Pi 3 and offered improved computing power, mainly due to the newly installed quad-core Broadcom BCM2837 with a clock speed of 1.2 GHz and 1 GB RAM.
2014
Raspberry Pi Compute Module
The first generation of the Compute Module was launched in 2014 and was a slimmed-down version of the Raspberry Pi Model B with a SODIMM form factor. It was equipped with a single-core Broadcom BCM2835 processor with 700 MHz and 512 MB RAM.
Revolution Pi – The Industrial Raspberry Pi since 2016
At the end of 2016, KUNBUS launched the RevPi Core, the first Revolution Pi controller based on the Raspberry Pi Compute Module (1st generation).
Conclusion: The Importance of the Raspberry Pi Compute Module for Industrial Applications and an Outlook for the Future
In conclusion, the Compute Module has paved the way for Raspberry Pi and open source in industrial applications. It has evolved from a computer designed for education to a robust, industrial-grade device. With its small size, flexibility and cost-effective performance, it has changed the way we think about embedded systems. With each new module, Raspberry Pi expands its potential and opens new doors for creative solutions. And the future? It looks bright. The next generation promises even more power, efficiency and adaptability. One thing is certain: the Raspberry Pi Compute Module is here to stay and continue to influence the industrial world.
Fazit: Die Bedeutung des Raspberry Pi Compute Modules für die industrielle Anwendung und ein Ausblick auf die Zukunft
Abschließend lässt sich sagen, dass das Compute Module den Weg für Raspberry Pi und Open Source in die industrielle Anwendung geebnet hat. Es hat sich von einem für die Lehre entwickelten Computer zu einem robusten, industrietauglichen Gerät entwickelt. Mit seiner geringen Größe, Flexibilität und kosteneffektiven Leistung hat es die Art und Weise, wie wir über eingebettete Systeme denken, verändert. Mit jedem neuen Modul erweitert Raspberry Pi sein Potenzial und öffnet neue Türen für kreative Lösungen. Und die Zukunft? Sie sieht strahlend aus. Die nächste Generation verspricht noch mehr Leistung, Effizienz und Anpassungsfähigkeit. Eines ist sicher: Das Raspberry Pi Compute Module ist hier, um zu bleiben und die industrielle Welt weiterhin zu beeinflussen.
