Pi R 2: An Advanced Computing Tool for the Modern Era

The world of computing has come a long way from the early days of punch cards and mainframes. With the advent of the Raspberry Pi – a small, affordable computer that could be used for various educational and hobbyist projects – computing technology has become accessible and democratised. But with the launch of the Raspberry Pi 2, there was a whole new level of potential for building complex systems and running complicated software that was previously out of reach. This article will explore the Raspberry Pi 2 (also known as Pi R 2) and compare it to its predecessor, the Raspberry Pi.

What is Raspberry Pi 2?

Before delving into the comparison between the two models, it’s important to understand what the Raspberry Pi 2 is. The Raspberry Pi 2 was launched in February 2015, as a successor to the Raspberry Pi Model B+. The device is a credit card-sized computer that can run a variety of operating systems, including Windows 10, Linux, and various other open-source software.

The Raspberry Pi 2 has an ARM Cortex-A7 quad-core processor running at 900MHz, which is a massive improvement over the single-core 700MHz processor of the original Raspberry Pi. It also has 1GB of RAM, allowing for more complex tasks and multitasking without sacrificing speed or stability.

One of the most significant benefits of the Raspberry Pi 2 is its compatibility with the HAT (Hardware Attached on Top) add-on boards, which make it possible to expand the functionality of the device. This means that the Pi R 2 can be used for a wide variety of applications, from building retro gaming systems to running web servers and everything in between.

Comparison to Raspberry Pi

While the Raspberry Pi 2 built upon the foundation of the original Raspberry Pi, it’s important to note some of the key differences between the two models. Below are some of the main differences that set the Raspberry Pi 2 apart from its predecessor:

1. Faster Processor:

The Raspberry Pi 2 is built around a quad-core Cortex-A7 processor clocked at 900MHz, which is significantly faster than the 700MHz single-core CPU in the original Raspberry Pi. This means that the Raspberry Pi 2 can handle more complex tasks and run multiple processes at once without sacrificing speed or stability.

2. More RAM and Storage:

The original Raspberry Pi had only 512MB of RAM, which was adequate for basic tasks but could be limiting when running more advanced applications. The Raspberry Pi 2, on the other hand, comes with 1GB of RAM, which is a significant upgrade. It also supports microSD cards up to 128GB, providing plenty of storage for a variety of applications.

3. HAT Compatibility:

The Raspberry Pi 2 is compatible with the HAT (Hardware Attached on Top) board, which allows for the addition of various sensors, interfaces, controllers, and other devices. This means that the Raspberry Pi 2 can be used for a wide range of applications, from building robots to controlling home automation systems.

4. Power Consumption:

The Raspberry Pi 2 may have a faster processor and more RAM, but it is surprisingly efficient when it comes to power consumption. It consumes around 2.1 watts at idle and 4.4 watts at maximum load, which is only slightly higher than the original Raspberry Pi.

5. Compatibility with Operating Systems:

While the original Raspberry Pi supported a range of operating systems, the Raspberry Pi 2 has even more options, including Windows 10 IoT for the development of Internet of Things (IoT) projects, Ubuntu, and various versions of Linux. This makes it easier for users to find an operating system that best suits their needs.


Q. Can I use Raspberry Pi 2 for gaming purposes?

A. Yes, Raspberry Pi 2 can be used for gaming. You can play retro games on it using various emulators, and even create your own gaming console using HAT modules.

Q. What are the applications of Raspberry Pi 2?

A. Raspberry Pi 2 has numerous applications, ranging from desktop computing to robotics, home automation, IoT, and even as a mini web server.

Q. How much does a Raspberry Pi 2 cost?

A. The Raspberry Pi 2 is available for around $35 USD, which is similar to the cost of the original Raspberry Pi. It is a very affordable computing tool that has limitless potential.

In conclusion, the Raspberry Pi 2 (Pi R 2) is a significant upgrade over the Raspberry Pi in terms of performance, memory, compatibility, and flexibility, making it a powerful computing tool for various applications. It is the perfect solution for hobbyists, students and professionals alike who want to experiment with new technologies, build new projects and solve complex problems. With its low cost and almost limitless potential, the Raspberry Pi 2 is an excellent option for those looking to enhance their computing capabilities.
