What is Raspberry Pi?

The Raspberry Pi is a small, affordable, and powerful single-board computer (SBC) developed by the Raspberry Pi Foundation. Designed to promote computing and programming education, it has become a favourite tool for hobbyists, students, and professionals alike. Raspberry Pi's versatility makes it a go-to choose for projects ranging from simple DIY electronics to complex industrial applications.

 

What is a Raspberry Pi?

A Raspberry Pi is a credit-card-sized computer that operates like a full-fledged PC. It runs an operating system (typically Linux-based, like Raspberry Pi OS) and supports a wide range of programming languages and hardware interfaces.

 

Key Features of Raspberry Pi

1. Compact Size: Portable and easy to integrate into projects.

2. Low Cost: Affordable compared to traditional computers.

3. Versatile: Supports programming, multimedia, and hardware projects.

4. Expandable: Can connect to sensors, actuators, and other peripherals.

 

Raspberry Pi Models

The Raspberry Pi family offers various models tailored to different needs:


1. Raspberry Pi Zero Series
  • Ultra-compact and low-power.

  • Ideal for embedded applications.

 

2. Raspberry Pi 4 Model B
  • High performance with up to 8GB RAM.

  • Suitable for desktops, servers, and multimedia applications.

 

3. Raspberry Pi Pico
  • Microcontroller-based board (not a full computer).

  • Perfect for small, low-power projects.
