Product Description: Universal 7x9cm Double-Sided PCB Board

The Universal 7x9cm Double-Sided PCB Protoboard is a high-quality general-purpose board designed for permanent soldering of electronic components. It features a standard 2.54mm (0.1-inch) hole pitch, compatible with most DIP (Dual Inline Package) components such as resistors, capacitors, ICs, headers, and connectors. The holes are pre-tinned with copper pads, allowing for easy soldering and reliable electrical conductivity.

Unlike single-sided boards, this double-sided PCB features conductive paths on both sides, enabling more efficient layouts and reducing the need for excessive jumper wires. This makes it ideal for compact designs and multilayer connections. With its generous 7x9cm (70x90mm) size, this protoboard provides plenty of space for mid-sized circuits or multiple smaller sub-circuits.

Whether you’re prototyping an Arduino-based device, experimenting with sensor arrays, or building a small power supply, this board ensures a clean and professional finish to your electronic projects.
