Raspberry Pi 2-3 Model B Multifunction Expansion GPIO Module

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

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.

This HAT for Raspberry has a lot of individual LED pixels to use it as a scrollable display. Control the brightness of its 119 pixels (17x7) individually by PWM and create animations or texts.

This fingeprint scanner from ADH-Tech combines a highly precise fingerprint sensor module with an onboard MCU and UART interface enabling trivially very connection to any project.

The scanner independently reads and analyses the fingerprint thanks to an MCU algorithm that can send a converted digital signal to a peripheral serial interface for a data read. The onboard MCU algorithm enables operations such as for example a fingerprint enroll.

Seeed Grove Arduino Starter kit is a game-changer for schools and robotic classes. You get a set of 10 sensors with a Arduino compatible board and 12 classes for only 28.99 EUR!

Raspberry Pi Pico HAT Expansion is an input/output expansion board designed for Raspberry Pi Pico, which provides a set of 2x20 pin headers in the form of Raspberry Pi header along with a set of 2 x 20 pins. It allows any HAT designed for Raspberry Pi to be connected to Raspberry Pi Pico.

This starter kit aims to quickly get you connected to Seeed Studio BeagleBone® Green. It contains 10 Grove modules and we provide you with 3 step-by-step projects to get you started quickly with all modules. The set comes in a handy box and is attractively priced!

This Serial Expansion HAT provides a 2-channel I2C and UART interface with 8 programmable GPIO Pins where you can connect more accessories and add-ons.

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.  

Ever needed a microphone for your project. This tiny little board will fulfill all your needs - it is not only mobile, but as well easy to connect. A low power, efficient, omnidirectional AMP401 microphone has an analog output. It works great for near and long range uses and is particularly suitable for a mobile projects given its extremely low energy consumption. You can use it in a range of applications - we can see it used in smartphones, cameras or electronic nannies.
