DS3231 Precision RTC Real Time Clock Module AVR ARM

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

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. Set of LEDs showing the current state of each of the channels. So if you need to get a light automation or garden sprinkling phasing set in place, this is the board just for you

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 tiny little board features two chips from Maxim Integrated: MAX32664 and MAX30101. The 30101 Oximetry module  is the sensor on board responding for both oximetry and heart rate sesnsing. The MAX32664 is equipped with a Cortex M4 handling algorithimc calculations, digital filtering and automatic gain control. The board comes with I2C and SparkFun has provided to it Qwiic connectors for ease of use.

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.

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 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!

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 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.
