article imageWorld's cheapest computer, Raspberry Pi, undergoes redesign

By Tim Sandle     Jul 14, 2014 in Technology
Cardiff - A new version of the Raspberry Pi, a basic computer system, has been released. Named the B+, the updated version uses less power than its predecessors and will cost about $35.
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. Although first developed in 2006, the models became widely available from 2012. The devices were originally made in China but they are now manufactured at Sony's Pencoed factory in South Wales.
The B+ is based on the same Broadcom chip as earlier versions and has the same 512Mb of memory. It does, however, contain some changes. The analogue and composite video connector has been replaced with a four-pole connector and the SD card slot has been replaced with a micro-SD card unit. There is also better power management, which means it can keep four USB peripherals going without requiring mains power or an external hub.
So popular has the computer been that in 2014 David Braben was appointed OBE in the Queen's Birthday Honours list. Braben was instrumental in helping to get the Raspberry Pi computer project up and running.
