Super Single Board Computer - Raspberry Pi 3
Raspberry Pi is a Single Board Computer, released on 29th February 2012 by the Raspberry Pi Foundation. Their aim is to produce a low-cost computer board for education, especially for underdeveloped countries. This year, Raspberry Pi celebrates its 4th birthday (or should we say 1st birthday because 29th February only occurs every 4 years?). Anyway, the Foundation has announced the new model of Raspberry Pi model B, the Raspberry Pi 3 with huge processor upgrades and new features. Let's take a look.
Here is the comparison of the packaging box of Raspberry Pi 2 (left) and Raspberry Pi 3 (Right). It is very obvious which is which! So do not worry that you might get the wrong version of Raspberry Pi.

Specifications: Raspberry Pi 3
SoC: Broadcom BCM2837
CPU: 4× ARM Cortex-A53, 1.2GHz
GPU: Broadcom VideoCore IV
RAM: 1GB LPDDR2 (900 MHz)
Networking: 10/100 Ethernet, 2.4GHz 802.11n wireless (WiFi)
Bluetooth: Bluetooth 4.1 Classic, Bluetooth Low Energy
Storage: MicroSD card
GPIO: 40-pin header, populated
Ports: HDMI, 3.5mm analog audio-video jack, 4× USB 2.0, Ethernet, Camera Serial Interface (CSI), Display Serial Interface (DSI)
It has a similar IO interface to Raspberry Pi 2. Dimension is the same, it still remains all the:
40-pin IO pin
microSD card socket (but it is not spring type)
4 x USB port
1 x Ethernet port
1 x HDMI port
1 x 3.5 analog audio-video jack
1 x Camera Serial Interface (CSI)
1 x Display Serial Interface (DSI)
As the dimension and all other IO interface ports are the same, the Raspberry Pi 2 casing will be compatible with Raspberry Pi 3.
Let's take a look at the improvements
Raspberry Pi 3 received a huge upgrade in processing power. From 32-bit (RPi 2) to 64-bit (RPi 3). Besides, RPi 2 is running at 900MHz, while Rpi 3 is running at 1.2GHz. I believe the 64-bit on Rpi 3 can only be utilized with the operating system, while Raspbian is yet 64-bit operating system (at the time I am writing this), but just looking at the system clock, Rpi 3 will outperform Rpi 2.
There is another small modification on Rpi 3 compared to Rpi 2, the Power LED and Activity LED have been moved to the edge of the power input (USB Micro-B socket) on Rpi 3. The reason is to give way to the 2.4GHz antenna. There is another huge upgrade on Rpi 3, it is integrated with WiFi and Bluetooth. It uses a Broadcom BCM43438 chip that provides 2.4GHz 802.11n wireless LAN, Bluetooth Low Energy, and Bluetooth 4.1 Classic radio. At the time this article is written Raspbian supported WiFi, but not Bluetooth. I believe it is just a matter of time before Bluetooth is fully supported.
With wireless connection support, Rpi 3 is designed for IoT development. Of course, you can always use it for an Internet connection.
