The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage - Wikipedia.
Tutorial kits are available for checkout to any student or teacher at the electronic support lab free of charge. These starter kits include everything necessary to learn the basics of the Raspberry Pi and include sensors, servos, Pi face and more all combined with an easy, self paced online tutorial to make Raspberry Pi simple to understand and integrate into your next project.
