The Raspberry Pi

The Raspberry Pi is a single-board computer that exists in various formats. It was developed in the UK and was originally designed to inspire young students to pursue interests in computer science. Since its release in 2012, there have been over 19 million Raspberry Pis sold. Currently, there are 9 different models of the Raspberry Pi sold. These are as follows:

• Raspberry Pi 4 Model B
• Raspberry Pi 3 Model A+
• Raspberry Pi 3 Model B+
• Raspberry Pi 3 Model B
• Raspberry Pi 2 Model B
• Raspberry Pi 1 Model B+
• Raspberry Pi 1 Model A+
• Raspberry Pi Zero W
• Raspberry Pi Zero

Prices start at 5 USD for the Raspberry Pi Zero and go up to 55 USD for the Raspberry Pi 4 Model B with 4 GB of RAM. The following is a picture of the Raspberry Pi 4 Model B with 4 GB of RAM:

The Raspberry Pi has been very popular with many projects, including IoT projects. My previous book, Internet of Things Programming Projects, uses the Raspberry Pi exclusively in the building of IoT-based projects including an internet-controlled robot car. As mentioned in Chapter 1, Introduction to Edge Analytics, the Raspberry Pi 4 Model B has brought the Raspberry Pi to desktop replacement levels. In fact, I am using this same model to write this book.
