Raspberry Pi 2
Raspberry Pi 2 Model B is the second edition of Raspberry Pi computers. Raspberry Pi 2 is much more powerful and faster than the original Raspberry Pi 1 Model B+, which was replaced by it in February 2015.
Raspberry Pi 2 Specifications:
- A 900MHz quad-core ARM Cortex-A7 CPU
- 1GB RAM
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot
- VideoCore IV 3D graphics core
Raspberry Pi 2 Benefits
Get personal with your Pi. Welcome to the Raspberry Pi™ 2, the single board computer that thinks it’s a home PC. Enhanced Quad Core Processor and 1GB RAM now provides you with the opportunity to:
- Build your own workstation – create and manage your documents and spreadsheets with ease using LibreOffice™
- Faster and more enjoyable gaming – experience less lag and more seamless gaming in all your favourites. Can’t wait to demolish buildings in Minecraft™, trigger your TNT now and be amazed by the results!
- No more buffer face – boots up Raspbian in less than half the time as the Model B+
- More power for your favourite projects – create Space Programs, Time Lapse Videos, GPS tracking, HD audio and lots more with a full ecosystem of supporting accessories.
- All your previous Raspberry Pi projects are 100% backward compatible with the new Raspberry Pi 2 Model B 1GB
Raspberry Pi 2 Features
- Broadcom BCM2836 Arm7 Quad Core Processor powered Single Board Computer running at 900MHz
- 1GB RAM so you can now run bigger and more powerful applications
- Identical board layout and footprint as the Model B+, so all cases and 3rd party add-on boards designed for the Model B+ will be fully compatible.
- Fully HAT compatible
- 40pin extended GPIO to enhance your “real world” projects. GPIO is 100% compatible with the Model B+ and A+ boards. First 26 pins are identical to the Model A and Model B boards to provide full backward compatibility across all boards.
- Connect a Raspberry Pi camera and touch screen display (each sold separately)
- Stream and watch Hi-definition video output at 1080P
- Micro SD slot for storing information and loading your operating systems.
- Advanced power management:
- You can now provide up to 1.2 AMP to the USB port – enabling you to connect more power hungry USB devices directly to the Raspberry PI. (This feature requires a 2Amp micro USB Power Supply)
- 10/100 Ethernet Port to quickly connect the Raspberry Pi to the Internet
- Combined 4-pole jack for connecting your stereo audio out and composite video out

The processor has completely changed on the new RaspberryPi 2, instead of a ARM v6 core chip (arm6l) the BCM2836 has been upgraded to an ARM v7 core which is a much more powerful core. However, your existing Raspberry Pi SD card images may not work because the firmware and kernel must be recompiled/adapted for the new processor. If you have a Raspberry Pi 2, and you are trying to upgrade your existing SD card, you will need to upgrade your installation. To do that, log into your Pi 1 and at a console or terminal type insudo apt-get upgrade to perform the upgrade procedure. You'll need your Pi to be on the Internet to do this. Once upgraded, the card will work on both Pi 1 and Pi 2 computers. If you have any pre-compiled binaries that you are downloading, those may need updating too, in order to take advantage of the speed increase. Anything where you have access to source code can be recompiled and ought to work just fine.
