Industrial Raspberry Pi: A Brief History and the Near Future

By ·Categories: Industrial IoT·Published On: March 31st, 2021·4.2 min read·

Raspberry Pi began its history a long way away from the world of business and industry. Intended to provide makers of all ages with a low-cost platform to learn the basics of coding, the first production Raspberry Pi was sold in 2012 for $30. The initial intention was not to make money or increase market-share, but instead to democratize access to hardware and coding knowledge. An industrial Raspberry Pi wasn’t on anyone’s radar at the time.

Maker Roots

The low cost, small size, and flexibility of this system on a chip meant the Raspberry Pi not only  provided access to technology for segments of the population that couldn’t afford a full desktop, but also inspired countless makers in garages, basements, and living rooms across the world.  

The Raspberry Pi community provided a resource to share ideas and help others develop their projects. Projects such as RetroPie, emulation software to play retro video games on a Raspberry Pi, and the “Magic Mirror” project, which embedded a Raspberry Pi into a mirror to display valuable content about the day ahead, such as the weather forecast and email.

Though these home projects made big splashes on social media, there remained a perception that the Raspberry Pi was a recreational computing device rather than a tool to be utilized for industrial applications. That perception still remains for many, though Industrial Raspberry Pi applications are continuing to gain exposure and popularity.

Rapid Prototyping on Pi

The early concept of an industrial Raspberry Pi evolved from the makers who were utilizing the system on a chip for hobbyist projects. Experiencing the ease and speed with which they could prototype and launch systems control and IoT projects, it only made sense to expand the use cases for the platform.

Developers themselves were the first to see the promise of industrial applications for Raspberry Pi. The ability to prototype end solutions on an inexpensive board made the cost of entry for system design much lower versus prototyping on desktop computers or industrial systems. Smart Home applications grew into Smart Building applications. IoT sensors for the home evolved into IoT sensors for industrial data collection.

Today, approximately 50% of Raspberry Pi end customers are utilizing them for commercial and industrial applications.

The Raspberry Pi Compute Module

“We are ready to take the wraps off something special, this time aimed at business and industrial users.”

In April 2014, James Adams, COO & Hardware Lead of Pi Trading announced the first Raspberry Pi Compute Module (CM) via their blog. It contained the “guts” of the Raspberry Pi integrated onto a small board designed to fit into a standard DDR2 SODIMM connector. Bearing a striking resemblance to a stick of RAM, the Compute Module was intended to be integrated into PCBs (Printed Circuit Boards), also commonly referred to as carrier boards. 

The release of the Raspberry Pi Compute Module was arguably the tipping point for industrial Raspberry Pi powered devices. Integrating a Raspberry Pi into application specific carrier boards allowed hardware designers to expand options for form factors and create expanded I/O connectivity options intended to serve their specific business or industry needs.

Flash forward to 2020 when Raspberry Pi released the fourth generation of their Compute Module. The CM4 offers the impressive capability gains of the Raspberry Pi 4, including a Broadcom BCM2711 quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz processor, OpenGL ES 3.0 graphics, and expanded memory options. Still designed for embedded applications, the form factor changed from the initial DDR2 SODIMM connector to a 2 x 100-pin high-density electrical interface connector.

Industrial Raspberry Pi Arrives

Originally teased a few months after the release of the fourth generation Compute Module, OnLogic unveiled the first details of our industrial Raspberry Pi powered computer on Pi Day, 3.14.21 to anyone who had signed up to receive more information. Nicknamed “One Tough Pi,” the system has been designed entirely in-house to bring the CM4 to Industrial and IoT applications.

Utilizing advanced thermal simulations, the OnLogic team designed an enclosure and thermal solution to optimize the Raspberry Pi for almost any environment. Representing the latest evolution of our Hardshell fanless technology, the resulting aluminum side panels provide structural rigidity while dissipating heat from internal components.

Inside the DIN-ready chassis, a custom designed carrier board will provide I/O built for industry, including 2 GbE LAN ports and a RS-232/422/485 Terminal Block. Dependable industrial wide-temp SSD storage takes the place of the eMMC storage found in many consumer grade solutions, providing higher capacity and faster transfer of data for industrial applications.

We have so much more that we’re excited to share, and this is just one of the CM4-based developments we’re working on. To be among the first to hear about what’s next for “One Tough Pi”, and beyond, visit OnLogic.com/industrial-raspberry-pi and sign up for more info.
