Raspberry Pi

Raspberry Pi is a series of low-cost, credit-card-sized single-board computers (SBCs) running Linux, designed for programming education and rapid prototyping.

The Raspberry Pi is a compact, high-performance computing platform: a low-cost, credit-card-sized single-board computer (SBC) designed to democratize programming. Since the 2012 launch, the Foundation has shipped over 68 million units, establishing it as the best-selling British computer of all time. Current models, including the flagship Raspberry Pi 5 and the ultra-low-cost Pi Zero, run the Linux-based Raspberry Pi OS and feature essential I/O: HDMI, USB ports, and General Purpose Input/Output (GPIO) pins. This hardware is deployed globally for diverse applications: industrial control, IoT projects (home automation), robotics, and embedded systems prototyping.
