Raspberry Pi 2 900MHz quad core ARM Cortex A7 CPU, 1GB LPDDR2 SDRAM, complete compatibility with 1

6x faster - Broadcom BCM2836 ARMv7 quad-core processor powered single board computer runs at 900 MHz Double memory - 1GB RAM, so you can now run larger and more powerful applications Identical plate layout and dimensions as the model B+, so that all cases and 3rd party add-on boards designed for the type B + will be fully compatible. 40pin expands GPIO to improve your "real world" projects. GPIO is 100% compatible with Model B+ and A+ boards. First 26 pins are identical to the Model A and Model B boards in full backward compatibility across all cards. Micro SD port for charging the operating system and storing data
