The Copper Prototype Perfboard 5x7cm is a compact and versatile prototyping PCB designed for building permanent electronic circuits using standard 2.54mm (0.1") spacing. It features individual copper pads and a clearly labelled grid layout, allowing components, headers, and jumper wires to be soldered directly for clean and reliable circuit construction. Its balanced rectangular size makes it suitable for medium density prototypes, sensor modules, and embedded system interfaces. Specifications Board size 50mm × 70mm 2.54mm (0.1") standard hole spacing Individual copper pad layout Green PCB solder mask finish Rows and columns labelled with numbers and letters Four corner mounting holes Compatible with standard through-hole components Features Versatile mid-sized perfboard for general prototyping Standard 2.54mm pitch for universal component compatibility Individual copper pads for flexible circuit design Clear grid markings for accurate and organised builds Durable solderable surface for permanent electronics projects Suitable for Arduino, ESP32, Raspberry Pi and sensor circuits Solderable Breadboard Alternatives Solderable breadboard-style PCBs provide a structured upgrade path from solderless breadboard prototypes into permanent circuits. These boards replicate standard breadboard internal connectivity using linked rows on the rear, allowing working prototypes to be transferred directly without redesign. Traces can also be cut or modified for custom routing where required.
