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 →Raspberry Pi Zero 2 W, the Zero footprint upgraded with a quad-core 64-bit Arm Cortex-A53 CPU and 512MB RAM. A real Linux computer that fits behind a small display or on the back of a robot, with on-board Wi-Fi/Bluetooth.
Good for IoT gateways, camera nodes, home-lab utilities, and embedded dashboards. Same size and mounting holes as Zero / Zero W.
