The Raspberry Pi Foundation has announced that its Model A computer is (finally) available for purchase in Europe. The Raspberry Pi Model A is the small computer that the foundation originally pitched as the low-cost $25 PC. The other computer is the Model B, which has been available for some time now. The Model A is a stripped down version of the Model B covered previously. It features a single USB port, and half of the RAM of the latest Model B at 256MB. Further, there is no Ethernet jack on the model B, so users wanting Internet access will have to grab a USB NIC.

The Model A is powered by the same Broadcom BCM2835 chipset as the Model B. That includes an ARM1176JZFS processor clocked at 700MHz and a Videocore 4 GPU. The GPU is capable of hardware accelerating H.264 video decodes at up to 1080p30 and 40Mbps video. The GPU is rated at 24 GLOPS general compute performance, and it supports the OpenGL ES2.0 and OpenVG libraries.
Interestingly, the Model A was originally planned to have a mere 128MB of RAM, but with the update of the Model B to 512MB RAM, the Raspberry Pi Foundation was also able to include twice the RAM in the Model A while maintaining the $25 price point.

The Model A reportedly uses as much as a third of the power as the Model B, which makes it ideal for projects that will run off of battery or renewable energy sources--like solar. The Raspberry Pi Foundation suggests that the Model A will be useful in robotics and networking projects, for example.
The Model A Raspberry Pi PC is currently available in Europe, but US availability is coming soon. It will cost $25, but you will also need at least an SD card for the operating system and a DC power source (like a cell phone wall charger with male micro USB connector). The promised $25 PC is finally here (at least for those on the other side of the pond). What will you be using it for?
