The Raspberry Pi 2 – Pi My Life Up

Pi 2

The Raspberry Pi 2 is the second generation of Raspberry Pi and

brought with it the first major hardware upgrade

of the Raspberry Pi. The Raspberry Pi 2 was the successor to the original Raspberry Pi B and B+. There were two releases of

the Raspberry Pi 2

Model B boards. The newer version contains a slightly more modern processor than the first version of the Pi 2.

The second revision of the Pi 2 is marked (v1.2), and the designation can be found printed on the Raspberry Pi’s circuit board.

The Raspberry Pi

2 is similar to the Raspberry Pi B+ in that it has the same base functionality and hardware design. However, it provided a huge step forward in the processing power of the Raspberry Pi.


Raspberry Pi team achieved the performance boost by swapping the weak single-core ARMv6 processor with a much more powerful quad-core ARMv7 processor that has a clock speed of 900


The CPU upgrade represented a four-fold increase in the number of cores and a 200 MHz increase in core speed. Overall, this created a nearly six-fold increase in performance compared to the original Raspberry Pi.

As the Pi 2 contains an ARMv7 processor, it was capable of running many more operating system distributions out of the box compared to the first generation Raspberry Pis.

This selection of operating systems includes Snappy Ubuntu core, Microsoft Windows 10 and the full range of ARM GNU/Linux distributions.


Pi 2 also boasts twice as much RAM as its

predecessor, bringing its total amount of RAM to 1GB.

Ultimately, this allows the Pi to handle much more resource-intensive tasks that the original Pi would struggle with


However, all of these performance improvements came at the cost of increased energy use. This power usage made the Raspberry Pi a little less useful for portable embedded projects.

The problem of portability was finally solved by creating the more energy-efficient, but weaker Raspberry Pi Zero.

The Pi 2 has now been replaced by the more powerful Raspberry Pi 3 and Raspberry Pi 4.
