Expansion Board GPIO Shield 40 Raspberry Pi B+ Pin

This module is used to extend the Raspberry's 40 GPIO pins to another set of 2x20 male pins and 8 parallel pins accessible on the terminal blocks in the that test leads are pushed. The electronic board offers great reliability with the Raspberry and is very easy to connect thanks to its existing suitable accessories but not included.
The module offers a set of mini jumpers to configure the GPIO.

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

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!

This touch HAT for Raspberry Pi will inspire your next interactive project with up to 12 capacitive touch sensors, from fruit keyboards to interactive lighting.

The kit includes 30 basic sensors, which will help you to easily kick-start any project. The sensors are featured with a proprietary Seeed Grove connectors enabling easy connection without soldering and a comprehensive guide book with exemplary classes.

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.

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.  

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
