Raspberry Pi Model A+ 256MB RAM 11 PI model A plus
The Model A+ is the low-cost variant of the Raspberry Pi. It is recommended for embedded projects and projects which require very low power, and which do not require Ethernet or multiple USB ports.
Raspberry Pi Model A+ 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.
Broadcom BCM2835 700MHz ARM1176JZFS processor with FPU and Videocore 4 GPU
