Types of Raspberry Pi

Raspberry Pi:

Raspberry Pi is credit card sized single board computer that can perform all the functions that a desktop computer can do by consuming less size, that’s what we have discussed on last tutorial if you haven’t studied it yet just take a look at last tutorial LINK.

In this tutorial we are going to discuss that what are the types of board raspberry Pi has produced and what are the advancements that has taken places in the past few years, we will take a tour of the last few years from the beginning to the end.
