The Raspberry Pi 2 is an upgraded version of the popular single-board computer, sporting a new processor and double the memory of previous models.
These changes offer greater capabilities, while still keeping the same form factor, the same price point and backward compatibility with the existing Raspberry Pi.
Announced at the start of February with immediate availability, the Raspberry Pi 2 keeps the same credit card footprint as the original Raspberry Pi, and is very similar in design to the Model B+ that was launched in 2014 (see comparison below - the new model is on top).
The Model B+ added more USB ports and an extended I/O connector block offering more inputs and outputs for hardware projects, but was based on the same system on a chip as the original Raspberry Pi.
With the latest update, the Raspberry Pi team is claiming to have made the device six times faster, in response to feedback from the education market where children learning to develop code were pushing the boundaries of the older hardware.
In addition, Raspberry Pi has recognised the huge uptake among the hobbyist or 'maker' community, as well as companies using the Pi for industrial purposes, and the increased capabilities reflect this also.
Potential buyers should note that the Raspberry Pi 2 still comes without a power adapter or a built-in operating system as standard in order to keep the price down, although distributors such as Element 14 and RS Components offer bundles with everything needed to get started.
