Adafruit Capacitive Touch HAT for Raspberry Pi - Mini Kit

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.

Ever needed a microphone for your project. This tiny little board will fulfill all your needs - it is not only mobile, but as well easy to connect. A low power, efficient, omnidirectional AMP401 microphone has an analog output. It works great for near and long range uses and is particularly suitable for a mobile projects given its extremely low energy consumption. You can use it in a range of applications - we can see it used in smartphones, cameras or electronic nannies.

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

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.

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.

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.
