This fingeprint scanner from ADH-Tech combines a highly precise fingerprint sensor module with an onboard MCU and UART interface enabling trivially very connection to any project.

The scanner independently reads and analyses the fingerprint thanks to an MCU algorithm that can send a converted digital signal to a peripheral serial interface for a data read. The onboard MCU algorithm enables operations such as for example a fingerprint enroll.

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.

The Pico Explorer Base is an expansion board for the Raspberry Pi Pico, designed to teach circuit properties and allow you to perform science experiments, build small robots and inventions. The board includes functional components such as a mini prototyping board, motor drivers, ADC and GPIO cables, a speaker, a display with four usable buttons, switches and Breakout Garden rails for the expansion module.

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 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.

The Qwiic HAT is an absolute basic of Qwiic system for Raspberry. It enables a quick and efficient connection of an sensor to your Raspberry over I2C bus (GND, 3.3 V, SDA and SCL). As Qwiic enables daisy chaining of components, you can pretty much install as many sensors on the Qwiic HAT as you want. On top of that it fits perfectly Pi Tin enclosure from SparkFun enabling connection while in case.

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.

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.
