2 Channel Relay Module 5V 10A for Arduino

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.

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 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!

The kit includes 40 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.

Pimoroni Fan is the best you can do for your new Raspberry 4! It is a well known fact, Raspberries can get hot. Even though, there are plenty of solutions to that, you will find no better than this Pimoroni Fan. It is a no-solder device, hence you can put it on and off as you wish

HAT kit with 2 DOF turn & tilt stand designed for Raspberry Pi. Includes the integrated PWM chip PCA9685 that allows RPi to control camera movement, and the TSL25911FN ambient light sensor that detects light intensity through the I2C interface.

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.

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.
