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

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.

The Grove Starter Kit for Arduino is one of the best Arduino starter kits for beginners. It includes an Arduino-compatible base shield and 14 additional Arduino sensors and accessories. With this Grove starter kit, you can create any Arduino project you want.

T-Cobbler GPIO KIT + 40-pin Grey Flat Cable Pi B+ RPI 2 RPI 3 RPI Zero features:

- Dimension: 6 x 7.3x 1.9mm
- Flat cable female / female 40 pins
- Total length: 25cm
- Quantity:
1x shield
1x flat cable

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.

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.  

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.

QWIIC is a connection standard developed by Sparkfun enabling a quick an easy connection of peripherals without a need to solder pins, without any mismatches due to polarized connector. And on top of that you can "daisy chain" them! 

This hat pretty much opens the whole QWIIC universe in front of your Pi. It features 4 QWIIC ports all on the same I2C bus (GND, 3.3V, SDA, and SCL).

A universal  2x20 GPIO makes it compatible with all Raspberry Pi boards, as well as Google Coral and Jetson Nano.

Note:  For a secure connection in some applications, you'll need to add a pair of 1x20 stackable headers to extend the pins to your cart.

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
