Appendix B. Raspberry Pi ports and legacy boards
In this appendix, you’ll find information about some of the Raspberry Pi ports and connections that we didn’t discuss in chapter 1. Our focus is on the Raspberry Pi 2 Model B. The connections and ports that we’ll cover in more detail include the following:
- Wireless internet connections using a USB Wi-Fi adapter
- 3.5 mm audio/video port
- Camera Serial Interface (CSI) port
- Ethernet port
- TV or monitor connection options
In section B.2 of this appendix, we’ll review key differences between the legacy Raspberry Pi 1 models as compared to the Raspberry Pi 2 Model B. We’ll look more at these popular, but older models:
- Raspberry Pi 1 Model B rev 2 (released September 2012)
- Raspberry Pi 1 Model B+ (released July 2014)
Let’s take a closer look at ports and connections.
The Raspberry Pi has many different ports, and you can connect many different things to it. In chapter 1, we covered most of the common ones you’ll use, but we’ll talk about a few of the other ports here. For reference, figure B.1 shows the ports and their typical uses for the Raspberry Pi 2 Model B.
Figure B.1. The Raspberry Pi 2 Model B has many different input and output ports that allow you to connect a keyboard or mouse, monitor, and even high-definition cameras.
Now let’s look in a little more detail at some of the ports and connections we didn’t cover in chapter 1 or in later chapters.
