A Raspberry Pi Model B+. Like mentioned below, this has more USB ports than the original Model B.
The Raspberry Pi 2 Model B in an updated version with more RAM, a much better processor, more USB ports and a larger GPIO header. It was released in February 2015.

The Raspberry Pi is a low-cost credit-card sized single-board[1] computer. The Raspberry Pi was created in the UK by the Raspberry Pi Foundation. The Raspberry Pi Foundation's goal is to "advance the education of adults and children, particularly in the field of computers, computer science and related subjects."[2] Many people have used the Raspberry Pi to make things like cameras, gaming machines, robots, web servers and media centres.

Versions

There are a few different versions of the Raspberry Pi, each made for different uses. All of the current versions use a microSD card for the operating system and file storage, are powered by a micro-USB port and have one HDMI port, one audio/video jack socket and a 40-pin GPIO connector This is a list of the current versions of the Raspberry Pi and their features.

  • Model A+: The Model A+ is cheaper, smaller and has fewer connectors than the other versions of the Raspberry Pi. It is made for use is small, low-power projects. It features a single-core 700 MHz ARM processor, 256MB RAM and one USB port.
  • Model B+: The Model B+ is more expensive than the Model A+ and has more connectors and RAM. It features a single-core 700 MHz ARM processor, 512MB RAM, four USB ports and one ethernet port.
  • Raspberry Pi 2, Model B: The Raspberry Pi 2 Model B is more expensive than the other versions of the Raspberry Pi and has much more RAM and a much faster processor. It features a quad-core 900MHz ARM processor, 1GB RAM, four USB ports and one ethernet port.

Features

  • The Raspberry Pi uses the ARM processor architecture, which is also used by most modern mobile phones.
  • The Raspberry Pi uses the Linux operating system instead of Microsoft Windows or Mac OS X like most computers.
  • The Raspberry Pi An operating system can be installed using NOOBS[3] (recommended), or by directly installing an operating system.
