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 M3 Hex Head Cap Screw Set (30mm) is a useful fastening kit for electronics, robotics, and mounting projects. The 30mm length works well for thicker parts, stacked builds, brackets, enclosures, and light frame assemblies. Its hex head design allows firm tightening with standard hex tools and helps reduce slipping during installation.
Great for makers, students, and hardware projects that need reliable M3 mounting screws.
Features:
Screw type: Low profile hex head cap screw
Screw drive type: Hex
Screw size: M3
Screw length: 30mm / 1.18in
Includes 10 screws
Includes 10 M3 nuts
Useful for circuit boards, sensors, and mechanical mounting
