This news comes to us from the official Raspberry Pi Foundation blog: Raspberry Pi Model A is now available for purchase from their official distributors in Europe. The less expensive board comes in at $25 and lacks ethernet, has only one USB port, and 256 megabytes of RAM as opposed to Model B’s 512. Besides the price, these changes come with an additional advantage: the Model A uses one third of the power of its big brother, which would make it great for battery-powered projects. If you’re not in Europe, you’ll have to hold tight for now; they expect to be shipping “very soon” to other parts of the world.
