First major redesign of Raspberry Pi unveiled
A new version of the credit card-sized computer, the Raspberry Pi, is launched today adding extra sensors and connectors to the £20 device.
The new model, known as B+, represents the first major redesign of the Raspberry Pi since its commercial launch and features four USB ports to enable the computer to support extra devices without their own mains power connection.
The computer is designed and manufactured in the UK as a way of promoting computer science to young people.
But it has also been widely embraced by the wider amateur and professional engineering communities and used for projects from home-made drones to creating industrial PCs that can control hundreds of devices.
The Raspberry Pi Foundation, the non-profit group that produces the device, hopes the extra connections and sensors will enable users to create bigger projects.
Eben Upton, CEO of Raspberry Pi Trading, said in a 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.’

The Raspberry Pi B+ is based on the same Broadcom BCM2835 Chipset and 512MB of RAM as the previous model.
It is powered by micro USB with AV connections through either HDMI or a new four-pole connector replacing the existing analogue audio and composite video ports.
The SD card slot has been replaced with a micro-SD, tidying up the board design and helping to protect the card from damage. The B+ board also now uses less power (600mA) than the Model B Board (750mA) when running.
It features a 40-pin extended GPIO, although the first 26 pins remain identical to the original Raspberry Pi Model B for 100% backward compatibility.
