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 →Compact u-blox NEO-6M GPS module for location tracking. Locks onto satellites and streams NMEA sentences over serial. Light enough for drones, RC vehicles, and robots.
Wires straight to Arduino, Raspberry Pi, ESP8266, ESP32, or STM32 over serial. The backup battery keeps the last position for faster reacquisition.
