Add-On Boards & HATs

The Raspberry Pi 2×20 pin connector allows additional daughter boards (known as HATs in Raspberry Pi lingo) to be connected to your Raspberry Pi. These boards can add all sorts of additional features and specialized functionality to your Pi and in most cases can even be stacked to allow for multiple HATs on a single Raspberry Pi! HATs can drive DC motors, control piles of servos, keep accurate record of time, or even have an LCD acting as a primary display. We also sell a prototyping HAT so you can build your own custom circuits directly on the Pi!
