system on a chip (SoC),which includes an
ARM1176JZF-S 700 MHz processor
• Video Core IV GPU
• originally shipped with 256 megabytes of
RAM, later upgraded to 512MB.
• It does not include a built-in hard disk , but
uses an SD card for booting and long-term
storage.

9. Accessories
• Camera – It can
produce 1080p, 720p and 640x480p video.
The dimensions are 25 mm x 20 mm x 9 mm.
• Gertboard – A Raspberry Pi Foundation
sanctioned device, designed for educational
purposes.
• Infrared Camera.
• HAT (Hardware Attached on Top) expansion
boards
