The Raspberry Pi 2 Model B is the second generation Raspberry Pi. Combining a six fold increase in processing power and a doubling of memory capacity with complete backward compatibility with the existing Model B Plus, Raspberry Pi 2 Model B is the perfect board for professionals and hobbyists alike. The new Raspberry Pi 2 Model B is jam packed with features. With a new quad core processor and twice the memory with a massive 1GB RAM. It’s a whopping 6x faster than its predecessor.
