If you are into prototyping with your Raspberry (which you should be given that is what the board is for), Pimeroni Explorer HAT Pro is a great solution for you. Board is equipped with a range of inputs and outpu, which enables it to achieve range of potential applications from controlling motors, to analog sensors and 5V systems. As any Pimeroni accessory it is well compatible with all Raspberry boards and comes in with a range of Pythong libraries on github issued by Pimeroni team themselves

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.

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.

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

This HAT is an open source portable sensor that provides the level of suspended particulate matter quantity with its mass. It has a powerful and high-tech PMSA003 sensor that provides the information of suspended particulate matter (PM1.0, PM2.5, PM10) in the air per unit volume.

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.
