Overview

The Raspberry Pi is a credit card-sized computer. The Raspberry Pi 2 Model B is the second generation Raspberry Pi. It is based on the BCM2836 system-on-chip (SoC), which includes an quad-core ARM Cortex-A7 processor and a powerful GPU. The Raspberry Pi supports various distributions of Linux including Debian, Fedora, and Arch Linux.

The Raspberry Pi was designed by the Raspberry Pi Foundation in order to provide an affordable platform for experimentation and education in computer programming. The Raspberry Pi can be used for many of the things that a normal desktop PC does, including word-processing, spreadsheets, high-definition video, games, and programming. USB devices such as keyboards and mice can be connected via the board’s four USB ports. Over five million Raspberry Pis have been sold, and lots of resources for the Raspberry Pi are available online.

The Raspberry Pi 2 Model B has the same form factor and connector locations as the older Raspberry Pi Model B+ and the newer Raspberry Pi 3 Model B. It has an ARMv7 processor, which means it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10.

With its 0.1″-spaced GPIO header and small size, the Raspberry Pi also works as a programmable controller in a wide variety of robotics and electronics applications. It can also be combined with our A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge to make a great controller for a small robot. We also carry a selection of Raspberry Pi expansion boards.

What you will need

To use the Raspberry Pi, you will need a few additional things that are not included:

  • A 5 V power source with a micro USB connector. We recommend this 5 VDC 1 A wall power adaptor and a USB A-to-Micro-B cable.
  • A microSD card with an operating system on it, which also serves as the main storage for the device.
  • Input and output devices, such as a keyboard and monitor.

You might also consider getting a case to house and protect your Raspberry Pi, such as the Translucent Enclosure for Raspberry Pi B+, 2 B, and 3 B.

While the Raspberry Pi is powered from a 5 V supply, it operates at a 3.3 V logic level and its pins are not 5V-tolerant. Connecting higher voltages, like 5 V, directly to an I/O pin could damage the board. We recommend you use something like our bidirectional logic level shifter to interface this board with 5V systems.

RTIMULib IMU library for embedded Linux systems
RTIMULib, written by richards-tech, is a library for embedded Linux systems designed to make it easy to interface with an IMU and get Kalman-filtered orientation estimates. It works with our MinIMU-9 v3, AltIMU-10 v3, and AltIMU-10 v4 (as well as the older MinIMU-9 v2 and AltIMU-10), and it includes two demo programs that aid in testing and calibrating the sensors. Instructions are provided for setting up RTIMULib on a Raspberry Pi.
