What you’ll learn

  • What are Hats and what do they offer?
  • Types of functionality available with Hats.
  • The range of potential applications with Hats.

Raspberry Pi Hats are specialized add-on boards that increase the Pi's capabilities and functions. The boards are engineered to fit the Pi’s GPIO header for seamless integration, removing the need for complex wiring or soldering. Hats come in various forms for any number of applications, including those for the IoT, such as adding sensors, motor drivers, automation capabilities, wireless communication, and more.

Hats can be used on nearly most Raspberry Pi models, allowing users to swap between them if needed. The plug-and-play design simplifies the integration of additional hardware, often with minimal to no need for software setup. In this roundup, we look at some of the latest Hats for IoT projects and their potential applications.

The future is poised for exciting developments and innovations as the Raspberry Pi ecosystem continues to expand, which could see Hats designed for prominent roles in advanced AI and sensing, edge computing, high-speed communications, and cloud integration. It will be interesting to see how that new technology will evolve over the next few years.
