Tiny Raspberry Pi computer gets redesign

Raspberry Pi B+

The credit card sized Raspberry Pi gains four USB slots and manages power usage significantly better than its predecessor.

The new Pi named the B+ was announced this morning and has already gone on sale in Australia, a few hours earlier than first expected.

Specification wise the Pi B+ isn't too different from its predecessor. It sports the same Broadcom chip with a 700MHz low power processor as the old Pi. It also contains the same 512MB of RAM.

The main changes on the new Pi are the two extra USB 2.0 ports; the old version only and whereas the Pi B+ now has four. In addition the B+ has ditched the larger SD card slot in favour of a Micro SD slot.

A more efficient power system on the B+ will mean the mini computer will be able to power all four USB ports without the need for to be connected to a main power socket or external hub.

The B+ also has a new audio circuit that "incorporates a dedicated low-noise power supply".

Founder of the Raspberry Pi Foundation, Eben Upton, has stressed that the B+ is not a replacement for the original Pi, but rather an evolution of the original device.

The founder also added in his statement: "We've been blown away by the projects that have been made possible through the original B boards and, with its new features, the B+ has massive potential to push the boundaries and drive further innovation."

It will cost £26 to purchase and will be available in some online electronics stores such as Element 14. Approximately 3 million of the first mini computers have been sold worldwide since its release in February 2012.
