Frequently Asked Questions

Q: What is an FR-4 prototype PCB and what can I build with it?

A: An FR-4 prototype PCB is a general-purpose printed circuit board made from fiberglass-reinforced epoxy laminate. It provides a stable, heat-resistant base for soldering electronic components. With this double-sided 4x6cm board, you can prototype circuits for Arduino projects, sensor modules, power supplies, LED drivers, signal conditioning, and a wide variety of DIY electronics builds.

Q: Is this PCB compatible with standard electronic components?

A: Yes. The board uses the industry-standard 2.54mm pitch spacing, which is compatible with virtually all through-hole components (resistors, capacitors, IC sockets, headers) as well as many SMD (Surface Mount Device) pads. It works seamlessly with components from popular platforms like Arduino and Raspberry Pi.

Q: What does "double-sided" and "tin-plated" mean for this PCB?

A: "Double-sided" means the board has copper traces on both the top and bottom surfaces, giving you more flexibility for routing connections and reducing the need for jumper wires. "Tin-plated" refers to the protective tin coating applied over the copper, which improves solderability, prevents oxidation, and ensures a reliable, long-lasting solder joint.
