Raspberry Pi HATs

Pimeroni Unicorn HAT is one of the most popular and at the same time easiest to use Raspberry HATs in Pimoroni offering. It is featured with a matrix of 64 RGB LEDs powered directly through the Pi board. The applications of the HAT spread from just a simple games in the classroom up to color indications in your robot. All of this accessible in a really straight forward way and supported by a range of Python libraries available on github and officially issued by Pimeroni. The hat is compatible with all Raspbery boards given its universal 40 GPIO pinout

If you are into prototyping with your Raspberry (which you should be given that is what the board is for), Pimeroni Explorer HAT Pro is a great solution for you. Board is equipped with a range of inputs and outpu, which enables it to achieve range of potential applications from controlling motors, to analog sensors and 5V systems. As any Pimeroni accessory it is well compatible with all Raspberry boards and comes in with a range of Pythong libraries on github issued by Pimeroni team themselves

Pimeroni Display-O-Tron is one of the most popular and at the same time easiest to use HATs in Pimoroni offering. It is featured with 16x3 character LCD supporting a complete ASCII character set. The shield is powered directly through the Pi board. The board comes with multiple capactive touch pads on top of that. All functions of the shield are accessible in a really straight forward way and supported by a range of Python libraries available on github and officially issued by Pimoroni. The hat is compatible with all Raspbery boards given its universal 40 GPIO pinout

Pimeroni Unicorn HAT HD is one of the most popular and at the same time easiest to use Raspberry HATs in Pimoroni offering. Compared to the Unicorn HAT it is equiped with twice as many LEDs in a row and a column giving a matrix of 256 LEDS! All of this accessible in a really straight forward way and supported by a range of Python libraries available on github and officially issued by Pimeroni. The hat is compatible with all Raspbery boards given its universal 40 GPIO pinout

The Pimeroni Automation HAT (PIM213) is a great solution for home automation. The controller board includes relays, powered outputs and buffered inputs up to 24V as well as analog channels.

Expansion Board GPIO Shield 40 Raspberry Pi B+ Pin features:
- Shield module for Raspberry Pi 2 and Pi 3, B and B +

Can't stand to run out of pins in your Raspberry Pi? You have a cool new accessory but there's no way to plug it in? If you answered yes to any of the above, then this pHAT could be just for you. This piece has 6 sets of 40 GPIOS - one for your Pi and the rest (5) for your collection of HATs that you might want to plug in at the same time. Use it for a specific project or just to play with several HATs at once.  

16 servo motors with one board seems impossible? With this board not only it isn´t impossible, but it even seems easy. Additionally, you won´t need to sacrifice any of your valuable GPIOs as the HAT connects directly via I2C. Additionally, you have a serial terminal connection at your disposal.

You can supply the power to the board through your Pi or directly if you are going for larger servos and would need a separate source of power. Simply scrap a small blob of solder on the isolation jumper.

You are looking for an easy way to program a microcontroller in your Arduino. It has never been easier - with this board you can do it in the record speed with support or Raspberry (or without for that matter, as the HAT works on the standalone basis as well). It was first developed as an in-house solution for Sparkfun production, and for its quality and usefulness ended up in mass production with a solid fan following.

The board includes several handy features ranging from the capacitive touch button for a standalone mode to launch programming, LEDs indicating the status of the program upload as well as some whiteboard labels to keep track of your projects.

QWIIC is a connection standard developed by Sparkfun enabling a quick an easy connection of peripherals without a need to solder pins, without any mismatches due to polarized connector. And on top of that you can "daisy chain" them! 

This hat pretty much opens the whole QWIIC universe in front of your Pi. It features 4 QWIIC ports all on the same I2C bus (GND, 3.3V, SDA, and SCL).

A universal  2x20 GPIO makes it compatible with all Raspberry Pi boards, as well as Google Coral and Jetson Nano.

Note:  For a secure connection in some applications, you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.
