The next-gen Raspberry Pi 2 runs on a 900MHz quad-core ARM Cortex-A7 CPU with 1GB LPDDR2 SDRAM. It offers six times faster and two times the memory of its predecessor. Raspberry Pi 2 also looks identical to Raspberry Pi 1. The connectors on the Raspberry Pi 2 are in the same place and have the same functionality, so existing users will find it easy to make the transition. Also, the board can still be run from a 5V micro-USB power adapter. All for $35, a bargain.
