Product Description:

The Raspberry Pi 2 Model B represents a major performance increase over its single-core based predecessors: up to six times faster in fact. As well as a new quad-core Cortex-A7 processor, the Raspberry Pi 2 Model B now features 1GB of RAM memory. The operating system kernel has been upgraded to take full advantage of the latest ARM Cortex-A7 technology and is available with the new version 1.4 of NOOBS software (See Note below). Backward application hardware and software compatibility has been maintained with the Raspberry Pi 1 Model A+/B+.

Features:

Broadcom BCM2836 900MHz ARM Cortex-A7 quad-core processor with VideoCore IV dual-core GPU

GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode
GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24GFLOPs with texture filtering and DMA infrastructure
1GB LPDDR2 SDRAM
HD 1080p video output
Composite video (PAL/NTSC) output
Stereo audio output
10/100 BaseT RJ45 Ethernet socket
HDMI 1.3 & 1.4 video/audio socket
3.5mm 4-pole audio/composite video out jack socket
4 x USB 2.0 sockets
15-way MPI CSI-2 connector for Raspberry Pi HD video camera
15-way Display Serial Interface connector
MicroSD card socket
Boots from MicroSD card, running a new version of the Linux operating system (See Note below)
40-pin header for GPIO and serial buses (compatible with Raspberry Pi 1 26-pin header)
Power supply: +5V @ 2A via microUSB socket
Dimensions: 86 x 56 x 20mm
Firmware looks for add-on boards that comply with the HAT (Hardware Attached on Top) design rules. This allows the Raspberry Pi 2 Model B to set up the GPIO and load drivers to suit an expansion board automatically.
