AJMRTC 10Pcs 5x7cm FR-4 Double Sided Universal Prototype PCB Board, 1.6mm Thick Perfboard Breadboard for Electronic Circuit Soldering, DIY Circuit Prototyping

AJMRTC double-sided universal prototype board is built with high-quality FR-4 glass fiber substrate, sized 5 by 7 centimeters with standard 1.6mm board thickness. The FR-4 material provides excellent insulation performance and mechanical strength, resisting deformation under soldering iron heat. Both sides are covered with tin-plated copper pads, supporting point-to-point soldering and jumper routing on two layers, which greatly improves wiring flexibility compared with single-sided perfboards. All through holes follow 2.54mm standard pitch, matching DIP ICs, resistors, capacitors, pin headers and other common through-hole electronic parts. The tin coating on pads prevents oxidation, keeps smooth soldering and reduces cold solder joints. It is widely used to build permanent circuits after successful breadboard testing, for Arduino peripheral modules, sensor circuits, power regulator boards and custom electronic repair modification. This package contains 10 prototype boards to meet multiple circuit development needs and spare backup.
