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 →Mini Universal PCT Compact Lever Connectors from Circuitrocks is ideal for DIY electronics builds.
Great for Arduino, ESP32, Raspberry Pi, and robotics or school projects here in the Philippines.
These compact lever connectors make wiring quick, safe, and effortless. Instead of struggling with traditional wire nuts or screws, you simply lift the lever, insert the wire, and snap it back down for a secure connection. The design works with both solid and stranded wires, making them perfect for a wide range of applications—from quick DIY fixes to more permanent electrical projects. Their reusable nature means you can adjust, remove, or rearrange connections without damaging the wire, saving you time and materials.
Ideal for home, workshop, or industrial use, these connectors help you achieve neat, organized, and reliable wiring with minimal effort. Whether you’re setting up lighting, repairing appliances, or building electronics projects, they provide a safe and convenient solution. Available in four variations—2-pin, 3-pin, 4-pin, and 5-pin—you can choose the configuration that best fits your wiring needs while enjoying the same user-friendly design and dependable performance.
