What is HAT?
HAT stands for "Hardware Attached on Top." Essentially, a HAT is a pre-built extension for your Raspberry Pi that allows it to perform some desired function. Most HATs are plug-and-play, requiring no soldering. And the best HATs automatically configure themselves. The EEPROM module communicates with the Raspberry Pi, telling it which IO pins it's using, how to configure them, and which drivers need to be installed.
What kinds of things can a Raspberry HAT do?
Anything! Well, that's not actually true. But you're certainly going to be surprised when you scroll down our list of Raspberry Pi HATs and learn all the cool things you can do just by plugging in an extension!
Unless noted otherwise, HATs do not come with a Raspberry Pi unit.
