SparkFun Qwiic pHAT v2.0 for Raspberry Pi

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 module is used to extend the Raspberry's 40 GPIO pins to another set of 2x20 male pins and 8 parallel pins accessible on the terminal blocks in the that test leads are pushed. The electronic board offers great reliability with the Raspberry and is very easy to connect thanks to its existing suitable accessories but not included.
The module offers a set of mini jumpers to configure the GPIO.

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 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

Raspberry Pi Pico HAT Expansion is an input/output expansion board designed for Raspberry Pi Pico, which provides a set of 2x20 pin headers in the form of Raspberry Pi header along with a set of 2 x 20 pins. It allows any HAT designed for Raspberry Pi to be connected to Raspberry Pi Pico.

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

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.

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

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
