The Arduino UNO Screw Terminal Block Shield is an expansion board that sits directly on top of an Arduino UNO and breaks out its pins into labeled screw terminals. Instead of pushing loose jumper wires into headers, you simply loosen a screw, insert your wire, and tighten it for a firm connection. It is ideal for hobbyists, students, makers, and anyone building irrigation controllers, sensor stations, or automation projects who wants neat, reliable wiring without constant soldering.
Key features
- Designed to fit the Arduino UNO pin layout for a direct, plug-on installation.
- Screw terminals let you connect and disconnect wires by hand, no soldering needed.
- Labeled pin breakouts make wiring easier to follow and troubleshoot.
- Holds wires firmly to reduce loose connections and accidental disconnects.
- Reusable across many projects as your build changes.
Typical uses
- Wiring sensors, relays, and modules for smart-garden and irrigation controllers.
- Prototyping and testing Arduino UNO projects on the bench.
- Student and classroom electronics projects.
- Home automation and DIY maker builds that need tidy, swappable connections.
How to choose / tips
- Confirm your board is an Arduino UNO (or UNO-compatible) so the shield aligns correctly.
- Use a small flat screwdriver and strip wire ends cleanly before clamping.
- Double-check each terminal label against your wiring diagram before powering on.
