ÿThe Raspberry Pi A+ features a smaller form-factor and an upgraded 512MB of RAM making it perfect when you need power and space efficiency. Otherwise it's the same capable little computer we've come to know and love. The Raspberry Pi A+ based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and an upgraded 512 Megabytes of RAM. This revision A+ board features four mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports. The design does not include a built-in hard disk or solid-state drive, instead relying on an microSD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems. The Raspberry Pi uses Linux-kernel based operating systems. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I2C interface. Board SpecificationsProcessor: ARM 700Mhz CPU
