Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The Raspberry Pi Pico 2 upgrades the beloved Pico platform with the powerful RP2350 microcontroller, dual cores up to 150 MHz, more SRAM, and modern security features. It keeps the same footprint and pinout as the original Pico, so you can drop it into existing designs and immediately benefit from the extra performance.
Whether you are building robots, IoT devices, test instruments, or complex control systems, Pico 2 gives you extra headroom for signal processing, control loops, and user interfaces while staying affordable and easy to program.
