Hands On: Raspberry Pi Model B

Model B is the higher-spec variant of the Raspberry Pi, with 512 MB of RAM, two USB ports and a 100mb Ethernet port. It’s the most popular model: It can be used to learn about computing; to power real-world projects (like home breweries, arcade machines, musical root vegetables, robot tanks and much more); as a web server; a bitcoin miner; or even play Minecraft.

THE RASPBERRY PI FOUNDATION unveiled the Raspberry Pi Model B+ earlier this month, boasting a new style and updated hardware over the previous Model B, which users welcomed with open arms.

Although not touted as Raspberry Pi Two but rather “the final evolution of the original Raspberry Pi”, the firm has tailored the Model B+ to include all of the additions that Raspberry Pi users requested.

While the layout has seen a slight shift around, most things haven’t changed and the general shape of the board remains the same.

Operating systems

The Raspberry Pi primarily uses Linux kernel-based operating systems.

The ARM11 chip at the heart of the Pi is based on version 6 of the ARM. The current releases of several popular versions of Linux, including Ubuntu.[58], will not run on the ARM11. It is not possible to run Windows on the Raspberry Pi.

The install manager for the Raspberry Pi is NOOBS. The OSs included with NOOBS are:

  • Archlinux ARM
  • OpenELEC[60]
  • Pidora (Fedora Remix)
  • Raspbmc[ and the XBMC open source digital media center
  • RISC OS[63] – The operating system of the first ARM-based computer
  • Raspbian (recommended) – Maintained independently of the Foundation; based on the ARM hard-float (armhf) Debian 7 ‘Wheezy’ architecture port originally designed for ARMv7 and later processors (with Jazelle RCT/ThumbEE, VFPv3, and NEON SIMD extensions), compiled for the more limited ARMv6 instruction set of the Raspberry Pi. A minimum size of 2 GB SD card is required, but a 4 GB SD card or above is recommended. There is a Pi Store for exchanging programs.
    • The Raspbian Server Edition is a stripped version with other software packages bundled as compared to the usual desktop computer oriented Raspbian.
    • The Wayland display server protocol enable the efficient use of the GPU for hardware accelerated GUI drawing functions.[70] on 16 April 2014 a GUI shell for Weston calledMaynard (software) was released.
    • PiBang Linux is derived from Raspbian.
    • Raspbian for Robots – A fork of Raspbian for robotics projects with LEGO, Grove, and Arduino.
