Rasperry Pi comes in different models. Raspberry Pi 1, Pi 2 and Pi 3 tells you of which generation the Pi is. And A, B, A+ and B+ is an indication for features which are new and were not in previous genereation. Here A is lower or has less features then B. And the model with “plus” (like A+ or B+) are greater than A or B that is from the prospective of features and power. There is one more Pi and it is Raspberry Pi Zero. The cost of Pi Zero is $5.
