Raspberry pie is a portable, powerful，and mini computer. The board length is only 85mm and width is only 56mm.Its size only as big as a credit card but it is a capable little PC. It can be used for many of the things that your desktop PC does, like high-definition video, spreadsheets, word-processing, games and more. Raspberry Pi also has more wide application range, such as music machines, parent detectors to weather stations, tweeting birdhouses with infra-red cameras, lightweight web server, home automation server, etc. It enables people of all ages to explore computing, learn to program and understand how computers work.
The Raspberry Pi Model B+ provides more GPIO, more USB than Model B. It also improves power consumption, audio circuit and SD card. It is more useful for embedded projects.
==Compare with Model B==
The Model B+ is the higher-spec variant of the Raspberry Pi. Compared to the Model B it has:
*More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
*More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hot plug and over current behavior.
*Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
*Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
*Better audio. The audio circuit incorporates a dedicated low-noise power supply.
*Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
