Raspberry Pi-based industrial PCs: A Cost-Effective Option

Introduction

Industrial PCs (IPCs) are an essential part of industrial applications such as automation of certain processes and HMI. The problem with traditional industrial PCs is that they are expensive and rigid. This limits the accessibility and customizability of traditional industrial PCs. But, today because of Raspberry Pi-based industrial PCs, IPCs are becoming a more and efficient alternative. The systems powered by Raspberry Pi Compute Modules, are for industries seeking cost-effective automation without compromising on performance.

Cost-Effectiveness and Affordability of Raspberry Pi-based industrial PCs

Raspberry Pi-based Industrial PCs (IPCs) are a cost-effective option for traditional industrial computers. They are not as expensive as traditional PCs because of the low-cost Raspberry Pi Compute Modules. The traditional industrial PCs have custom-built motherboards and other such costly components. The Raspberry Pi-based IPCs use standardized modules which reduces manufacturing costs. Moreover, they run on open-source software, which eliminates licensing fees. They have certain long-term benefits. Their low power consumption helps to produce cost-efficient solutions. Furthermore, connectivity options like RS232, RS485, USB, Ethernet, and GPIO makes integration with current industrial equipment. These IPCs support Raspberry Pi OS, Ubuntu, and Android. One can select an operating system that suits the needs of the operation without extra licensing costs. Combining affordability, flexibility, and efficiency, Raspberry Pi-based IPCs are a great choice for industrial applications, and edge computing applications, offering a scalable and budget-friendly solution.

Raspberry Pi-based Industrial PCs (IPCs) offer a cost-effective alternative to traditional industrial computers. They use low-cost, standardized modules and open-source software, reducing manufacturing and licensing costs. With benefits including low power consumption, customizable design, and multiple connectivity options, these IPCs provide a scalable, budget-friendly solution for industrial and edge computing applications, supporting various operating systems.

CM4 vs. CM5 Comparison

Figure 1: Differences between CM4 and CM5 based IPCs

The above table focuses on key differences between the two Compute Modules. While CM4 and CM5 both offer industrial-grade quality operations, CM5 is good at processing power, making it better suited for applications such as AI-driven automation and edge computing. On the other hand, CM4-based IPCs remain a great choice for general industrial automation due to their lower cost and reliable performance.

Real-World Use Cases & Challenges

Industries worldwide are implementing Raspberry Pi-based IPCs for automation, AI, and IoT applications. In manufacturing, IPCs are used for monitoring production lines, and AI-driven analytics to improve efficiency and reduce downtime. The retail sector uses RPi-based IPCs utilizing their low power consumption and cost-effectiveness. Additionally, Industrial IoT applications utilize RPi IPCs for remote applications. These IPCs allow industries to reduce operational costs and improve energy efficiency. Despite their benefits, Raspberry Pi-based IPCs also have limitations. There are processing power constraints, as these devices still lack the performance levels of high-end x86-based industrial PCs. The absence of x86 architecture also creates compatibility challenges with legacy industrial software. Proper security configurations are also required while deploying RPi-based systems in critical environments.

The Future Aspects of Raspberry Pi-based industrial PCs

As technology evolves, Raspberry Pi-powered IPCs are expected to improve over time. Future iterations of Raspberry Pi Compute Modules will be using more efficient processors, better AI capabilities, and improved security. Additionally, the adoption of 5G connectivity and edge AI will add more usage to current models. Also increasing support for industrial protocols such as Modbus, PROFINET, and MQTT, makes Raspberry Pi IPCs more compatible with existing industrial control systems.

Conclusion

Raspberry Pi-based industrial PCs have emerged as a cost-effective and reliable industrial applications. By offering powerful performance, energy efficiency, and rich connectivity options, they provide an excellent alternative to traditional IPCs. With Compute Module 5 introducing higher processing power and AI capabilities, these devices are now suitable for even more advanced automation and edge computing tasks. As industries continue to adopt smart and AI-driven solutions, Raspberry Pi-powered IPCs will play an increasingly important role in shaping the future of industrial computing.
