When I first heard about the Raspberry Pi, I wasn’t really interested because it wasn’t something new to me. A few years ago, I had experimented with an ARM-based development board (S3C6410 series, as shown in the image below). Although there were some differences between that board and the Raspberry Pi—like its larger size, lack of HDMI port, no built-in touchscreen, and a slightly lower price—it didn’t seem like a big deal to me at the time. I thought the performance and cost-effectiveness were comparable. However, due to a poor user experience and work-related reasons, I stopped using it after just a few days and eventually sold it two years later. That left me with a rather negative impression of ARM development boards, so I didn’t pay much attention to the Raspberry Pi’s updates afterward.
**ARM**
ARM is a British company known for designing the ARM architecture, which is primarily used in 32-bit processors. These are chip designs, not software, and they are widely used across many industries. Companies like Samsung and Apple license ARM technology to build their own chips.
It's important to note that ARM itself doesn't manufacture chips. Instead, it licenses its processor designs to semiconductor companies, who then customize and produce their own versions. In my understanding, ARM provides the core technical blueprint for processors, and other companies add their own peripherals and features to create their own chips. All chips that use ARM's licensed technology are referred to as "ARM-based."
**Raspberry Pi**
The Raspberry Pi is a small circuit board that runs on an ARM processor and can run either Linux or Windows. It functions like a mini desktop computer, designed to be affordable and accessible.
Developed by the Raspberry Pi Foundation, a UK-based charity, the project was led by Eben Upton. In March 2012, he officially launched what was then considered the world’s smallest desktop computer—a credit-card-sized device capable of performing basic computing tasks. The foundation's goal was to promote computer science education in schools and make computing more engaging for students.
The Raspberry Pi integrates most of the components you’d find in a traditional computer into a single board. While it connects to a monitor, keyboard, and mouse similarly to a regular PC, it runs on a Linux-based operating system.
Over time, the Raspberry Pi has evolved into a versatile tool used in both educational and hobbyist projects around the world. Its affordability and flexibility have made it popular among developers, educators, and tech enthusiasts alike.
