Types of Raspberry Pi HATs
HATs primary to types could be split in input (sensors), output (actuators) and adapter boards, however many of them actually combines all of these functions (especially IoT focused HATs). The key categories by application would include most likely motor/ servo boards (enabling movement), sensor boards (enabling collecting information about board environment including temperature, pressure, current location, gestures, light and many others), communication (across the range of protocols from bluetooth to WiFi), audio and display HATs. One thing is sure and that is that no matter what project you have come up with, there potentially is a board for that already.
Raspberry Pi HATs key providers
Similarly to Arduino, there is a range of producers supporting Raspberry with their own designs of shields with the most recognized being Pimoroni, Waveshare and PiHut or JustBoom. Additionally, there is a wide range of offering from generalists such us Adafruit, Sparkfun, Seed and Pololu. We benefit from several official distribution agreements with the most renowned providers and for the others offer the most popular products. No matter the provider we always try to provide the best products in the competitive prices. Look through the category and our producer pages to learn more.
