Are you an electronics hobbyist, student, or maker looking for reliable, affordable prototyping solutions? Look no further! This Universal PCB Protoboard Set offers six different standard sizes — 7x9cm, 6x8cm, 5x7cm, 4x6cm, 3x7cm, and 2x8cm — all in one convenient package, perfect for a wide range of DIY circuit projects.
Each board features double-sided copper-clad design with pre-drilled holes on a 0.1-inch grid, making it ideal for through-hole components. Whether you’re building Arduino shields, sensor modules, audio circuits, or custom power supplies, these protoboards provide a sturdy, clean platform for soldering and testing your designs.
The pre-tinned pads ensure excellent solderability and reduce oxidation, while the FR-4 substrate offers good mechanical strength and thermal resistance — essential for durable prototypes. The variety of sizes lets you match the board to your project’s footprint, minimizing waste and maximizing efficiency.
With nearly 3,000 units sold and consistently positive feedback, this protoboard set has proven popular among educators, engineers, and hobbyists worldwide. At just $2.70, it’s an unbeatable value — especially when compared to buying individual boards or expensive development kits.
Whether you’re stocking up your workshop, teaching a electronics class, or starting your next invention, this set gives you the flexibility and reliability you need without breaking the bank.
