What is Raspberry Pi?

by Robotistan Shopify 02 Aug 2023

The Raspberry Pi is a low-priced, credit card-sized computer created by Raspberry Pi Foundation. This single-board computer can be plugged into a TV or computer monitor and used with a standard keyboard and mouse. It’s a versatile small device that can be used by all ages to develop programming skills and discover computing. It does everything you’d expect a desktop computer to do, such as watching videos, preparing documents, playing games, and writing code. In addition to this, the Raspberry Pi can be used in a wide array of projects. Let’s talk about these Raspberry Pi Projects.


What Can Be Done with Raspberry Pi?

  • Learning and Education: The Raspberry Pi is an excellent device for learning programming. You can use various platforms such as Arduino IDE, Thonny IDE and VS Code (which are a text-based programming platforms) as well as block-based languages like Scratch, MicroBlocks, etc. It allows users to explore coding and electronics in a hands-on way.
  • Do It Yourself (DIY) Projects: Raspberry Pi can be used to create “do-it-yourself” projects. Some of these projects are smart home lights, robotic cars, weather station systems, door lock systems, etc.
  • Internet of Things (IoT) Applications: Its small size makes it suitable for various IoT projects, such as sensor monitoring, an IoT fan, smart mirror, voice assistant, and attendance systems.
  • Home Automation: Raspberry Pi can be integrated into smart home projects to control smart devices like lights and other smart devices.
  • Web Browsing: It can be used as a web browsing machine, allowing users to access the internet and perform online activities.
  • Media Streaming: Raspberry Pi can be turned into a media center using software like Kodi, which enables users to stream and play media files on their TV.
  • Security Systems: These can be used in creating DIY home security systems with cameras and sensors.
  • Office Tasks: It can handle word processing, spreadsheets, and other office-related tasks with applications.

    Raspberry Pi Models

Of course, these are not all the projects you can make by using a Raspberry Pi. There are many projects you can make with this development board. However, while all models of Raspberry Pi are designed to be versatile, they are not identical, and there are differences between each model. Each new series of the Raspberry Pi typically offers improvements in terms of performance, connectivity, and features. As a result, different models can be used in different tasks, and some may not be capable of certain functions due to hardware limitations. Let’s examine Raspberry Pi Models.


What are the Raspberry Pi Models?

There are many models of Raspberry Pi. However, we’re not going to go through every one of them in detail.

  • Raspberry Pi 1 Model A / B / B+ / A+: Raspberry Pi 1 series is the first-generation Raspberry Pi Model. This basic kit has laid the foundation for future Raspberry Pi Models.
  • Raspberry Pi 2 Model B: It was released in 2015. Raspberry Pi 2 Model B created a difference from Raspberry Pi 1 in the processor. The Raspberry Pi 2 Model B is powered by a Broadcom BCM 2836 processor, which is a powerful ARM Cortex-A7 based quad-core processor that runs at 900MHz.
  • Raspberry Pi 3 Model B / B+: These models were released in 2016 and 2018, respectively. They came with built-in Wi-Fi and Bluetooth, which extend the possibilities of your projects. In addition to this, Raspberry Pi 3 has a 1.2 GHz quad-core processor, representing a significant upgrade from the Raspberry Pi 2.
  • Raspberry Pi 4 Model B: The Raspberry Pi 4 Model B is the most powerful model to date among other Raspberry Pi models. This board can be used for a wide range of applications, including multimedia, entertainment, home assistant, weather station, etc. The main difference between Raspberry Pi 4 and others is processor speed, which allows for faster performance and more RAM capacity.
  • Raspberry Pi Zero: This board doesn’t include a Wi-Fi or Bluetooth module. It’s half the size of a Model A+ but with twice the utility.
  • Raspberry Pi Zero W: Thanks to the addition of wireless LAN and Bluetooth, the Raspberry Pi Zero W is ideal for making embedded Internet of Things (IoT) projects. This ultra-compact board is perfect for small and portable projects.
  • Raspberry Pi Zero 2 W: The Raspberry Pi Zero 2W offers improved performance over its predecessor. It can be used in similar applications as the Raspberry Pi Zero W but with more capabilities and processing power.
  • Raspberry Pi 400: Featuring a quad-core 64-bit processor, 4GB of RAM, wireless networking, dual-display output, and 4K video playback, as well as a 40-pin GPIO header, Raspberry Pi 400 is a powerful, easy-to-use computer built into a neat and portable keyboard.
  • Raspberry Pi Pico: This board is a microcontroller board. It’s different from the Raspberry Pi single-board computers we got used to. It’s not a full-fledged computer with an operating system but rather a microcontroller.



There is a specific Raspberry Pi model that I'd like to talk about the most. This model is Raspberry Pi Pico. This will be the topic of the next blog. Our article about “What’s Raspberry Pi?” ends here. Thank you for your time.
