A Single Board Computer (SBC) is a fully functional computer built on a single circuit board. It includes all the essential components of a traditional computer, such as:

• Processor (CPU) – The brain of the computer, handling all computations.
• Memory (RAM) – Temporary storage for active processes.
• Storage – Can be built-in (eMMC, NAND flash) or external (microSD, SSD, USB storage).
• Input/Output (I/O) Ports – USB, HDMI, GPIO (General-Purpose Input/Output), Ethernet, and more.
• Power Management – Often runs on low power (e.g., 5V via USB or DC input).

Common Examples of SBCs

• Raspberry Pi – The most popular SBC used for learning, IoT, robotics, and more.
• BeagleBone Black – A powerful board often used for industrial applications.
• Arduino (with add-ons like Linux-based shields) – While not a full SBC on its own, it can be used as part of an SBC system.
• Odroid, LattePanda, ASUS Tinker Board – Alternative SBCs for different performance and connectivity needs.

Uses of SBCs

• Education & Programming – Great for learning to code, teaching electronics, and developing software.
• IoT & Embedded Systems – Used in smart devices, automation, and sensor-based applications.
• Media Centers & Home Servers – Can be used as a media player (Kodi), NAS, or lightweight server.
• Robotics & DIY Projects – Powers drones, robots, and interactive hardware projects.
• Digital Signage – To show messages, videos, and images to a target audience.

SBCs are popular because they are compact, low-cost, power-efficient, and versatile, making them useful for hobbyists, engineers, and even commercial applications.
