Raspberry Pi 3 Model B
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.

The size of the Pi 2 and Pi 3 boards are the same.
There is slight change in component placement to allow addition of WiFi / Bluetooth SoC & Chip antenna in Pi 3.
System on Chip (SoC)¶
Broadcom BCM2837 SoC
ARM Cortex-A53 Processor (ARM V8 ISA)
- 400 MHz
- Videocore IV Multimedia Co-Processor
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.
Repositioned RUN pin-header¶
The RUN pin-header is also repositioned
WiFi / Bluetooth SoC BCM43438¶
WiFi and Bluetooth 4.1 (Classic and LE) are provided by Broadcom BCM43438 chip
