The Raspberry Pi family has been a game-changer in the world of affordable computing, offering a range of options for hobbyists, educators, and even small-scale manufacturers. While most people are familiar with the flagship Raspberry Pi Model B series, there’s another, more specialized member of the Pi family that often goes unnoticed: the Raspberry Pi Compute Module 4. This compact and powerful device is not your typical Raspberry Pi, and it’s aimed at a different audience altogether.
What Sets the Compute Module 4 Apart?
Unlike the more popular Raspberry Pi models, which come with a variety of ports and connectors, the Compute Module 4 is a bare-bones, straight-shooting rectangle. It lacks the visible ports that make other Raspberry Pi models so user-friendly. This absence of built-in connectors makes it less intuitive for the average user but opens up a world of possibilities for developers and manufacturers.
System on a Chip (SoC)
The heart of any Raspberry Pi is its Broadcom System on a Chip (SoC). Imagine taking a CPU, GPU, and RAM and condensing them into a single, compact package—that’s what an SoC does. While the Model B series is limited by its small form factor, the Compute Module 4 is designed to unleash the full potential of its SoC. This makes it ideal for applications that require more power and flexibility than what the standard Raspberry Pi can offer.
Customization and Price Range
The Compute Module 4 offers various configurations, including built-in eMMC storage options. Prices range from $20 for the most basic version to $90 for the high-end model, making it the most expensive Raspberry Pi available. This price range allows you to choose the right combination of storage and memory for your specific needs.
Carrier Boards: The Key to Connectivity
To use the Compute Module 4, you’ll need a specially designed carrier board. These boards provide the ports and connectors that the module itself lacks. The official Raspberry Pi Foundation carrier board costs around $35, but there are cheaper alternatives available online. However, it’s essential to note that less expensive boards may limit the module’s capabilities.
Who is the Compute Module 4 For?
Given its complexity and price point, the Compute Module 4 is not aimed at the casual user or beginner. Instead, it’s designed for developers and manufacturers who want to integrate the power of Raspberry Pi into their own products. Whether you’re developing a smart home device, an industrial automation system, or any other specialized application, the Compute Module 4 offers the flexibility and power you need.
Extended Features
The official Raspberry Pi carrier board comes with a host of extended features, including dual HDMI outputs, dual camera ports, and even a PCIe port for PCIe cards. These features make the Compute Module 4 a supercharged Raspberry Pi, capable of handling a wide range of tasks that go beyond the capabilities of the standard models.
Getting Started
Setting up the Compute Module 4 is similar to other Raspberry Pi models. You’ll need an 8GB or larger microSD card to burn the Raspberry Pi OS image onto. Insert the card into the carrier board, connect your peripherals, and power it up using a 12-volt barrel connector (note that it can’t be powered via micro USB). Once set up, you’ll have a powerful, flexible computing platform at your disposal.
Conclusion
The Raspberry Pi Compute Module 4 is a specialized tool designed for specialized tasks. While it may not be suitable for everyone, it offers unparalleled flexibility and power for those who know how to harness it. If you’re a developer or manufacturer looking to integrate Raspberry Pi technology into your products, the Compute Module 4 could be the perfect solution for you.
