Exploring Raspberry Pi: The Ultimate Single-Board Computer

The Raspberry Pi is a series of affordable, credit card-sized single-board computers (SBCs) developed by the Raspberry Pi Foundation, a UK-based charity. Since its launch in 2012, it has transformed computing education and made digital innovation accessible to people worldwide. Whether you're a student, hobbyist, or tech enthusiast, Raspberry Pi offers a powerful and budget-friendly way to dive into programming, hardware projects, and more.

Evolution of Raspberry Pi

The Raspberry Pi started with a 700MHz single-core CPU and 256MB RAM, and over the years, it has evolved into more powerful models like the Raspberry Pi 4, which boasts a quad-core CPU (1.5GHz) and up to 8GB RAM. Despite these advancements, Raspberry Pi has maintained its affordability, with flagship models priced under $100 and the ultra-cheap Raspberry Pi Zero available for just $5.
