رسپبری پای مدل A+ مناسب برای کاربردهایی با عدم نیاز به دسترسی به اینترنت و اتصالات USB زیاد
The Model A+ is the low-cost variant of the Raspberry Pi. It replaced the original Model A in November 2014. Compared to the Model A 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.
-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 further reduced power consumption.
-Better audio. The audio circuit incorporates a dedicated low-noise power supply.
-Smaller, neater form factor. We’ve aligned the USB connector with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes. Model A+ is approximately 2cm shorter than the Model A.
We recommend the Model A+ for for embedded projects and projects which require very low power, and which do not require Ethernet or multiple USB ports.
