The Copper Prototype Perfboard 3x7cm is a compact prototyping PCB designed for building permanent electronic circuits using standard 2.54mm (0.1") spacing. Featuring individual copper pads and a clear labelled grid, it allows components, headers, and jumper wires to be soldered directly for clean and reliable circuit construction. Its rectangular form factor makes it ideal for small embedded projects, sensor modules, and custom interface boards. Specifications Board size 30mm × 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 Compact perfboard for space-efficient circuit design Standard 2.54mm pitch for universal compatibility Individual copper pads for flexible prototyping Clear grid markings for accurate component placement Durable solderable construction for permanent builds 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 to 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 when required.
