Raspberry Pi gets even tinier with new Model A+ board

The new version of the popular microcomputer sports a microSD card slot and an even more compact design.

Raspberry Pi, the programable microcomputer, has become even more micro. A newly unveiled board adds a few tempting hardware tweaks, as well as reducing the overall size of the Pi.

Raspberry Pi represents an effort to strip a computer down to its most basic elements, providing only a simple, undecorated circuit board that can be hooked up to a monitor and other peripherals -- or baked into more ambitious and bizarre projects. It offers a way for youngsters to get to grips with programming, and a very cheap way for grown-up geeks to get experimental.

The new A+ board measures 65mm (2.6 inches) in length, compared with the older 86mm (3.4-inch) Model A board. The Raspberry Pi Foundation, based in Cambridge, UK, has also seen fit to swap the Pi's SD card slot for a microSD option, and pop in a 40-pin GPIO header, giving more inputs and outputs.

The Foundation boasts that its new board features an audio circuit with a dedicated low-noise power supply, while the A+ keeps the 256MB of RAM that its forebear possessed.

The A+ is designed to serve as a more modest companion to the powerful B+ board , revealed in the summer. Brits can buy the A+ now for a little over £15 from retailer Farnell, while US shoppers can find it at MCM for $20.

"It's pretty mind-bending to be able to knock another $5 off the cost while continuing to build it here in the UK," writes Raspberry Pi founder Eben Upton.
