Universal Prototype PCB Board 15×20cm — Double-Sided FR4 for Electronics Projects

Universal Prototype PCB Board — 15×20 cm, Double-Sided FR4

The 15×20 cm universal prototype PCB board is the mid-large format prototyping board — large enough for complex multi-stage circuits, compact enough for most project enclosures. With a double-sided FR4 fiberglass substrate and a 2.54mm (0.1") pitch through-hole grid, it accepts all standard DIP ICs, resistors, capacitors, transistors, and connectors without adapters.

Key Features

• 15×20 cm working area — mid-large format, fits most standard project enclosures
• Double-sided copper layer — solder on both sides for denser routing and ground plane connections
• FR4 fiberglass substrate — rigid, dimensionally stable, rated for standard soldering temperatures
• 2.54mm (0.1") pitch through-hole grid — compatible with all standard DIP components, pin headers, and connectors
• Tin-plated through-holes — excellent solderability, corrosion-resistant pads

Typical Applications

• Arduino and Raspberry Pi multi-stage circuit builds
• Power supply and voltage regulator prototyping
• Audio amplifier and filter circuit assembly
• Motor driver and relay control circuit prototyping
• Custom PCB replacement and repair boards
