This is the chapter web page to support the content in Chapter 1 of the book: Exploring Raspberry Pi – Interfacing to the Real World with Embedded Linux. The summary introduction to the chapter is as follows:

In this chapter, you are introduced to the Raspberry Pi (RPi) platform hardware. The chapter focuses on recently released Raspberry Pi models and describes the various subsystems and physical inputs/outputs of the boards. In addition, the chapter lists accessories that can prove helpful in developing your own Raspberry Pi-based projects. By the end of this chapter, you should have an appreciation of the power and complexity of this physical-computing platform. You should also be aware of the first steps to take to protect your board from physical damage.

Learning Outcomes

After completing this chapter, you should be able to:

  • Describe the capability of the Raspberry Pi (RPi) and its suitability for different project types.
  • Describe the major hardware systems and subsystems on the RPi boards.
  • Identify important accessories that you can buy to enhance the capability of your RPi.
  • Have an appreciation of the power and complexity of the RPi as a physical computing platform.
  • Be aware of the first steps to take in protecting your board from physical damage

Digital Media Resources

Here the digital resources referred to in the chapter web page are provided. There are high-resolution versions of some of the important figures and links to videos, resources and websites that are described in the chapter.

Raspberry Pi Poster

The Raspberry Pi Poster is available for download as high-resolution PNG raster format and a high-resolution PDF vector-mapped format images using the following links:

The poster images are large format images that have been rendered for an A3 page size, which is 11.69″ x 16.53″ (29.7cm x 42.0cm) in dimension.


There has been a recent update to the Raspberry Pi Zero which now means that you can attach the camera to the CSI adapter that is present on the edge of new Raspberry Pi Zero boards. This means that the Zero is now a very suitable board for video streaming applications, especially where weight is a consideration.

Products Described in this Chapter

Here are links to some of the products that are used in this chapter. Please do your own due diligence on these products and the retailers that are identified:


The USB-to-serial UART TTL cable is used throughout  this book, for debugging problems with the Raspberry Pi, for viewing and interacting with the console as the board is booting and finally it is used for programming a low-cost Arduino Pro (3.3V) module. There are several products available such as those on Amazon: There is an official TTL-232R-3V3 cable, and lower cost alternatives (that have not been tested) such as the GearMo 3.3V Header-like TTL-232R-3V3 cable.

It is also very useful to have a 2A-3A 5V regulated power supply, especially if you are planning to use the Raspberry Pi 3 or connecting the Raspberry Pi to a Wi-Fi adapter, USB webcam or LCD display. Here are a few such examples: Raspberry Pi Power supplies on

Other very useful accessories include:

Manufacturing the Raspberry Pi

Metropolis Multimedia has provided a short video that shows the manufacturing of the Raspberry Pi board at the Sony facility in Wales, UK. The use of automated visual inspection in the development cycle is particularly impressive.
