Raspberry Pi® is an ARM based credit card sized SBC(Single Board Computer) created by Raspberry Pi Foundation. Raspberry Pi runs Debian based GNU/Linux operating system Raspbian and ports of many other OSes exist for this SBC.
Raspberry Pi Foundation has announced a new version Raspberry Pi 3. Read announcement here. With on-board WiFi / Bluetooth support and an 64bit improved Processor, Raspberry Pi v3 will be an exciting board for Makers, Engineers and Students.

Broadcom BCM2837 SoC
A ceramic chip antenna is used by WiFi and Bluetooth 4.1 SoC BCM43438. The chip antenna moves the indicator LEDs that were present in Pi 2 to the lower side of PCB.
The ACT and PWR LEDs are repositioned as shown below in Raspberry Pi 3 when compared to Pi 2.
The RUN pin-header is also repositioned
WiFi and Bluetooth 4.1 (Classic and LE) are provided by Broadcom BCM43438 chip
