Pimoroni Unicorn HAT HD

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

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!

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.

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

Sense HAT is your absolute classic used for a well-known and popular Astro Pi projects. It features set of sensors (Pressure, humidity, IMU and temperature) and a great 8x8 LED screen. It is a full set for your Raspberry - you can both measure your projects environment, display it on the screen as well as manouver and input data with joystick and buttons included on the HAT.

This little board is simply a I2C board to Qwiic converter. It pretty much enables any device with I2C connectors to work with Qwiic system. It has two Qwiic ports - both of them served with the same I2C bus. You simply stick the board on your I2C board and get additional two Qwiic ports. It is as easy as it sounds

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.

The Qwiic HAT is an absolute basic of Qwiic system for Raspberry. It enables a quick and efficient connection of an sensor to your Raspberry over I2C bus (GND, 3.3 V, SDA and SCL). As Qwiic enables daisy chaining of components, you can pretty much install as many sensors on the Qwiic HAT as you want. On top of that it fits perfectly Pi Tin enclosure from SparkFun enabling connection while in case.

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.
