Universal Prototype PCB Board 20×30cm — Double-Sided FR4 for Electronics Projects

Universal Prototype PCB Board — 20×30 cm, Double-Sided FR4

The 20×30 cm universal prototype PCB board is the largest standard-size prototyping board in the Keszoox range — ideal for complex multi-stage circuits, power supply designs, and large-scale Arduino or Raspberry Pi projects that outgrow smaller boards. 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

• 20×30 cm working area — the largest standard prototype board size, ideal for complex multi-stage circuit designs
• 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
• Pre-drilled holes — no drilling required; insert components and solder directly

Typical Applications

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