Raspberry PI Model A is credit-card sized computer, capable of doingmany things that your desktop PC does, like spreadsheets, word-processing andgames. It also plays high-definition video. It can run several flavors of Linuxand is being used to teach kids all over the world how to program. Though theModel A lacks half the RAM of the Model B, a USB2.0, and the 10/100 EthernetUSB adapter, the price should definitely make up for it.

 

The secret sauce that makes this computer so small and powerful is theBroadcom BCM2835, a System-on-Chip that contains an ARM1176JZFS with floatingpoint, running at 700 Mhz, and a Video core 4 GPU. The GPU provides Open GL ES2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decodes and iscapable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute.What's that all mean? It means that if you plug the Raspberry Pi into yourHDTV, you could watch BluRay quality video, using H.264 at 40MBits/s.

 

The system volume lives on an SD card, so it's easy to prepare, runand debug several different operating systems on the same hardware. Most Linuxdistributions for the Pi will happily live on a 2GB SD card but larger cardsare supported.

 

The Model A's built-in USB port provide enough connectivity for aWi-Fi adapter, mouse, or keyboard, but if you want to add more you can use aUSB hub. It is recommended that you use a powered hub so as not to overtax theon-board voltage regulator. Powering the Raspberry Pi is easy; just plug anyUSB power supply into the micro-USB port. There's no power button so the Piwill begin to boot as soon as power is applied, to turn it off simply removepower.

 

On top of all that, the low-level peripherals on the Pi make it greatfor hardware hacking. The 0.1" spaced GPIO header on the Pi gives youaccess to 8 GPIO, UART, I2C, SPI as well as 3.3 and 5V sources. Mating ribboncables can be found in the related products below.
