The Little Computer That Could: Remembering the Raspberry Pi 3

In the ever-evolving landscape of single-board computers, the Raspberry Pi 3 holds a special place. It wasn’t the first Pi, but it was arguably the model that truly brought the power of accessible computing to the masses. For years, it served as the workhorse for countless DIY projects, educational initiatives, and hobbyist endeavors, proving that small size didn’t mean small potential.

While newer, more powerful iterations like the Raspberry Pi 4 and 5 have since emerged, the Pi 3 remains a capable and relevant board, especially for those just starting their maker journey or tackling projects with moderate processing demands. Let’s take a trip down memory lane and appreciate what made the Raspberry Pi 3 so impactful.

A Significant Step Up:

Released in 2016, the Raspberry Pi 3 represented a substantial leap forward from its predecessors. The key upgrade was the introduction of a 64-bit quad-core ARM Cortex-A53 processor clocked at 1.2GHz. This marked a significant performance boost, making it noticeably faster and more responsive for a wider range of tasks. Finally, running a full desktop environment felt less like a novelty and more like a viable option for basic computing.

Beyond the raw processing power, the Pi 3 also integrated onboard Wi-Fi (802.11n) and Bluetooth 4.1. This was a game-changer, eliminating the need for cumbersome USB dongles for wireless connectivity and opening up a world of possibilities for IoT (Internet of Things) projects and wireless control.

Key Features That Made it Shine:

• Quad-Core Power: The 64-bit processor provided a significant performance uplift, allowing for smoother multitasking and the ability to run more demanding applications.
• Integrated Wireless: Onboard Wi-Fi and Bluetooth simplified setup and enabled a wider range of wireless projects without the need for extra hardware.
• Familiar Form Factor: Maintaining the credit-card-sized footprint and the 40-pin GPIO header ensured compatibility with a vast ecosystem of existing HATs (Hardware Attached on Top) and accessories.
• Affordability: Staying true to the Raspberry Pi Foundation’s mission, the Pi 3 remained incredibly affordable, making it accessible to educators, students, and hobbyists on a budget.
• Active Community: By the time the Pi 3 was released, a vibrant and supportive online community had already formed around the Raspberry Pi. This meant a wealth of tutorials, projects, and troubleshooting resources were readily available.

What Could You Do With a Raspberry Pi 3?

The versatility of the Raspberry Pi 3 fueled an explosion of creative projects:

• Retro Gaming Emulation: Its increased processing power made it a popular choice for building retro gaming consoles using emulators like RetroPie.
• Media Center: Running software like Kodi transformed the Pi 3 into a capable media streamer for enjoying movies, TV shows, and music.
• Basic Desktop Computing: For light web browsing, email, and document editing, the Pi 3 could serve as a surprisingly functional desktop.
• Home Automation: It became a central hub for controlling smart home devices and automating tasks using platforms like Home Assistant.
• Educational Tool: The Pi 3 was widely adopted in schools and universities for teaching programming, robotics, and computer science.
• IoT Projects: Its onboard Wi-Fi and Bluetooth made it ideal for connecting sensors, controlling devices remotely, and building internet-connected gadgets.
• Robotics: Interfacing with motors, sensors, and cameras via the GPIO pins allowed for the creation of various robotic projects.

A Lasting Legacy:

While the Raspberry Pi 3 might not be the latest and greatest anymore, its impact on the world of DIY electronics is undeniable. It democratized computing, empowered countless creators, and laid the foundation for the even more powerful boards that followed. It remains a capable and cost-effective option for many projects, especially those that don’t require the absolute cutting-edge performance of newer models.
