10PCS Keyestudio Prototype P CB Board For Arduino UNO R3 Shield Board FR-4 Environmentally Friendly

This pack of ten Keyestudio prototype PCB boards is designed specifically for creating custom shields for your Arduino UNO R3. It is ideal for South African students, makers, and electronics hobbyists looking to transition their breadboard designs into permanent, reliable circuits.

Seamless Arduino UNO integration

These prototype boards are designed to match the Arduino UNO R3 form factor perfectly. By soldering standard 2.54mm pitch pin headers to the through-holes, you can plug the completed shield directly into your UNO R3 controller.

High-quality FR-4 construction

Built from durable, environmentally friendly FR-4 material, these double-sided PCBs feature plated-through holes for reliable electrical connections. The robust design ensures your custom circuits remain stable during prototyping and final deployment.

Standard spacing for easy component mounting

The boards feature a standard 2.54mm hole pitch and a 1.0mm hole diameter, making them compatible with a wide range of electronic components. You can solder components directly onto the through-holes to build your custom circuits.

Secure mounting and breadboard compatibility

Each board includes four 3mm fixed mounting holes to securely fasten your completed project. Additionally, the layout allows you to stick a tiny breadboard onto the prototyping area for solderless testing with jumper wires.
