Pimoroni Explorer HAT Pro

Expansion Board GPIO Shield 40 Raspberry Pi B+ Pin features:
- Shield module for Raspberry Pi 2 and Pi 3, B and B +

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.

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

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.  

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

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.
