Overview of the most significant features of the new Raspberry Pi 2 in comparison to its older brothers, Raspberry Pi Model B and Model B+.

 


Introduction

As the package with the new Raspberry Pi 2 came, I decided to write a short overview of the new device and to mention the “first glance” differences in comparison to its older brother Raspberry Pi Model B.

Buying

As I live in one of the countries of the third world, I don’t have an opportunity to buy directly from element14.com or some other official RPi distributor. So my choice was to order it on ebay.com from seller twoplushkcom. It was worth 39.55$ including Economy Int’l Shipping shipping to Ukraine. It came in a nice box with a quick start guide.

Characteristics

  • A 900MHz quad-core ARM Cortex-A7 CPU (~6x RPi B performance )
  • 1GB LPDDR2 SDRAM (2x memory)
  • 40pin extended GPIO.
  • 4 x USB ports(2 ports in RPI B)
  • 4 pole Stereo output and Composite video port
  • Full size HDMI
  • CSI camera port for connecting the Raspberry Pi camera
  • DSI display port for connecting the Raspberry Pi touch screen display
  • Micro SD port for loading your operating system and storing data
  • Micro USB power source
  • 1.2 Amp to the USB ports (2A power supply needed)
  • Ethernet
  • Windows 10 IOT compatible

Improvements

There are plenty improvements in the RPi, if you compare it to Model B, a little bit less putting it side-by-side with Model B+.

The thing is that RPi Model B+ had some worthy changes in the board structure, even though the processor and memmory remained the same. They decided to put 4 full size usb-ports, 4pole stereo output, 40 instead of 26 GPIO ports on the board, optimize power consumption. The board now has 4 installation holes, so you can properly screw it to any case or custom cradle you want. It doesn’t need an SD card adapter any longer, because there is a micro-sd port on the board. There was a problem with the small USB output current (e.g a WebCamera on a long wire didn’t power up), so they fixed the problem, raising the maximum power reserve for USB ports up to 6 Watts.

All of these advantages appear to be very helpful after making my first RPi project, when I had to use a Hub to connect 3 USB devices, to forget about using a simple microphone and to dream of more GPIO ports.

Windows 10 IOT support

Yes, Raspberry has done a lot of work together with Microsoft recently, to make this happen. There is now a completely free version of Windows 10 IOT Core , optimized to work on some popular IOT boards such as Arduino, Raspberry etc. In fact, Microsoft has started making a huge move in the IOT area, creating this OS. They have various versions of it, to fill different needs:Windows-10-IoT.png

There is a nice article about running Windows 10 IOT on the RPI 2 aspects.

 

Summary

It is a really nice and powerful device, which is being constantly improved and has a great constantly growing community, which can help begginers to become experts. It gives you an opportunity to build that IOT prototype of your dream and is a nice way to start your experience in the are.
