Understanding Single Board Computers (SBCs)
A single board computer is a self-contained computing device that integrates all the essential components of a traditional computer onto a single board. These components typically include a microprocessor, memory (RAM), storage, and various input/output interfaces. What sets SBCs apart is their compact size and the ability to run complete operating systems like Linux, making them highly versatile for a multitude of tasks.
Key Features of Single Board Computers
SBCs come with different types of processors, ranging from energy-efficient ARM-based processors to more powerful x86 processors. The choice of processor determines the overall computing power and capabilities of the SBC.
The amount of RAM affects the system’s multitasking capabilities. More RAM allows for smoother performance when running multiple applications simultaneously.
SBCs typically use microSD cards or onboard eMMC storage for data storage. The choice of storage depends on the project requirements and the need for higher data transfer speeds.
Connectivity options vary between different SBCs. Common features include USB ports, HDMI or other display interfaces, Ethernet, and wireless connectivity such as Wi-Fi and Bluetooth.
GPIO (General Purpose Input/Output)
GPIO pins allow the SBC to interact with the physical world. This is crucial for projects involving sensors, actuators, and other hardware components.
Operating System (OS) Compatibility
SBCs support various operating systems, with Linux being a popular choice due to its lightweight nature. Some SBCs also support Windows or other operating systems, depending on the architecture.
