My favorite is the Matrix Creator. This is because it has just about every sensor on it including a microphone array. It even has a place where a camera can be mounted in its center. So, if I don't need a screen attached to the Pi, I pretty much will have this attached.
- 8 MEMS microphone array (DIY Amazon Echo)
- FPGA (Xilinx Spartan 6)
- Microcontroller (ARM Cortex M3)
- Temperature sensor
- Ultraviolet sensor
- Pressure sensor
- 3D accelerometer
- 3D gyroscope
- 3D magnetometer
- Humidity sensor
For a classroom environment, you don't need much else than it to have unlimited projects.
Ya its a pretty versatile hat that's for sure and for the price point its even better having everything packed into one plus the multiple languages compatibility its certainly one that stands out on its own and a great community around it.
Machine Learning BrainCraft HAT for Raspberry Pi 4.
It has accelerometers, switches, LEDs and a graphical display plus interfaces for a camera, microphones, speakers, I2C etc.
I used to like the ChipKIT Pi which allowed arduino applications to work on a Pi, but I think it has been retired.
I actually managed to pick up one of ChipKit's have not had a chance to play with it but did manage to get a image for it as I couldn't find much for documentation on it. Have not heard of the other will have to check into that one.

The Pimoroni FAN Shim is great for cooling and I always equip my builds with one.
I also like the Pimoroni LED Shim and the Blinkt - they're both excellent at displaying cluster information visually (such as Docker info or CPU usage).
The OhEye HAT is also nice - provides 16 analog inputs and 10 more digital inputs that you can enhance with 10k resistors. I went through hoops to get one.
Fedora. Or Baseball.
Just kidding - I've not actually used "hats" on the regular. Aside from evaluating a few add-on boards prior to the HAT standard being finalised, I really don't use them on a regular basis. I find it easier just to use things which are mass-market USB peripherals or use smaller microcontrollers to work with hardware directly (and then it'd be shields, or more frequently, modules).
Hey everyone just thought I would toss the question out there and see if I can find something new others might recommend when it comes to Raspberry Pi Hats.
So with that being said.
Whats your favorite/favorites Raspberry Pi Hats and why?
Pictures are always good too!
