IdentiPi - Fingerprint HAT for Pico

Introducing Fingerprint HAT for Raspberry Pi Pico - an innovative solution for secure biometric authentication. This HAT is an ideal tool for developing unique projects and applications thanks to its ease of use with some simple commands, you do not have to know any fingerprint technology or the module infrastructure.

Experience rapid and stable fingerprint verification with our Fingerprint HAT. Features include a commercial fingerprinting algorithm, capacitive sensitive detection, and highly integrated hardware for small-scale applications. The narrow stainless-steel rim allows for 360° omnidirectional verification. Simplify your biometric needs effortlessly!

The 1.14" TFT display provides a pleasant user experience and the 5-way joystick allows you to add programmable controls to your project.
