What are HATs?
HAT overlays are modules intended for installation on Raspberry Pi (Pi HAT) or Raspberry Pi Pico (Pico HAT) boards. They have standard connectors, enabling installation without the need for soldering. These include many power supply systems, sensors, pin expanders and communication modules. Their manufacturers often provide ready-to-use libraries and usage examples, making their use even easier.
