Raspberry Pi Hats

Raspberry Pi HATs (Hardware Attached on Top) expand the functionality of Raspberry Pi computers by providing dedicated hardware interfaces and specialised capabilities. These add-on boards connect directly to the 40-pin GPIO header, offering compact, stackable solutions for projects requiring sensors, communication modules, motor control, or AI acceleration.

Applications range from precise positioning and navigation using GNSS modules, to advanced AI processing with built-in accelerators, and easy integration of servo motors or environmental sensors. Performance factors include compatibility with various Raspberry Pi models, ease of stacking or breakout options, and reliable signal quality. HATs often simplify wiring and reduce project complexity while maintaining flexibility for prototyping and development in robotics, automation, and embedded systems.
