The different flavors of a Raspberry Pi
The Raspberry Pi Foundation has released four major models of the Raspberry Pi com-
puter. They the are Model A, Model B, Model B+, and Model A+. The Raspberry Pi's CPU
is the Broadcom BCM2835 chip. It contains an ARM processor running at 700 MHz and a
powerful graphics chip. The board features HDMI and Composite (RCA) video outputs,
USB ports, two expansion slots, a Micro USB port for power, and an array of GPIO
( General-purpose input/output ) pins to interact with the outside world.
Since all models share the same basic hardware platform, all the examples in this topic are
applicable to all the versions.
