A Second Serving of Pi(e)

Do we have a tinkerer in the house? If you are this is the device for you. What started off as a simple board to teach programming to kids by the raspberry pi foundation in the UK, it has become one of the more popular system on a board on the market now.  It has since gotten new form factors and now, a new upgrade. Say hello to the Raspberry Pi 2.2

On the outset it still has the same form factor as the original model B. There are a few significant changes however –  the placement of the ports has been switched around, the location of the camera and DSI ports are also different in the Pi 2. Furthermore, the Pi2 has similar complements of post as the B+ – namely four USB ports, a gigabit Ethernet port, combo audio and composite video port, and a full sized HDMI port.  Like it’s brothers the Pi2 uses a 5 volt microUSB jack for power.

Loading the operating system onto the Pi2 is done by the micro SD card slot-  an upgrade from the original SD slot. It runs primarily Linux, but Microsoft just announced a Windows 10 version that supports the Pi2 called Windows 10 IoT, or Internet of Things.

What makes the Raspberry Pi2 more than just a mini computer is the included GPIO pins, which can be used in multitudes of ways for a project. All you need to do is to create scripts to access the pins to link to hardware connected to it. There are a bunch of projects that is available online –  ranging from simple home automation to complex robotic builds. The sky is the limited by your imagination.
