The Raspberry Pi is a series of small, single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. Originally designed to promote basic computer science education in schools and developing countries, it has become an incredibly popular tool for hobbyists, engineers, makers, and industrial developers worldwide due to its low cost, high modularity, open design, and active community.
- System on a Chip (SoC): Integrates the CPU, GPU, and RAM onto a single silicon chip (primarily Broadcom chips).
- ARM Architecture: Uses energy-efficient ARM processors, meaning standard x86/x64 Windows or Linux software must be compiled specifically for ARM (ARMv6, ARMv7, or ARM64) to run.
- GPIO Pins: General Purpose Input/Output pins allow direct interaction with external hardware like sensors, motors, LEDs, and relays.
- MicroSD Card Storage: Typically boots from a MicroSD card acting as its solid-state drive, though newer models support high-speed USB 3.0 booting and NVMe M.2 SSDs via PCIe.
- Linux Native: While multiple systems exist, the primary and officially supported OS is Raspberry Pi OS (formerly Raspbian), a highly optimized derivative of Debian Linux.
Over the years, the Raspberry Pi family has expanded. Selecting the right board depends heavily on your computational needs, budget, power restrictions, and form factor limits.
