Specification

Compared to the Model A it has:

 More GPIO pins. The GPIO header has grown to 40 pins, while retaining the same

pinout for the first 26 pins as the Model A and B.

 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

power consumption was reduced by between 0.5W and 1W.

 Better audio. The audio circuit incorporates a dedicated low-noise power supply.

 Smaller neater form factor. The USB connector was aligned with the board edge,

moved composite video onto the 3.5mm jack, and four squarely-placed mounting

holes were added. Model A+ is approximately 2cm shorter than the Model A.
