A new version of the Raspberry Pi barebones computer has been released.
Called the B+, the updated version uses less power than its predecessors and will cost about $35 (£20).
The B+ can also power more peripherals without the need for a dedicated power source and has more connectors to help link it to other devices.
The new model is released as the Pi faces increasing competition from other tiny computers.
Michael Powell of Element14 - one of several electronic component retailers offering the new product - gave an overview of the machine, at a launch event.
