5×7cm DIY Prototype PCB Universal Perfboard 2.54mm Pitch (5-Pack)

5×7cm DIY Prototype PCB Universal Perfboard — 2.54mm Pitch (5-Pack)

This 5×7cm universal prototype PCB (perfboard) provides a grid of 2.54mm pitch through-hole pads for soldering permanent circuits after breadboard prototyping. Made from FR4 fiberglass with single-sided copper pads, it accommodates DIP ICs, through-hole components, and module headers — the essential step between breadboard prototype and custom PCB.

Why Choose This Perfboard?

• FR4 Substrate — Superior mechanical strength and moisture resistance vs. phenolic (FR2) boards
• 2.54mm Standard Pitch — Compatible with all DIP ICs, Arduino headers, and standard through-hole components
• Individual Pads — Each hole has its own isolated copper pad; connect with solder bridges or wire links
• 5×7cm Size — Fits most project enclosures; large enough for Arduino shield-sized circuits
• Pack of 5 — Multiple boards for iterative prototyping and different projects

Typical Applications

• Permanent soldered version of breadboard Arduino projects
• Sensor breakout and interface board fabrication
• Custom Arduino shield construction
• Power supply and regulator circuit assembly
• Electronics education soldering practice
• Small production run circuit assembly

Tips for Perfboard Wiring

• Use solid-core 22–24 AWG wire for point-to-point connections between pads
• Plan component placement before soldering — sketch the layout on paper first
• Use IC sockets for DIP ICs to allow replacement without desoldering
• Apply flux before soldering for clean, reliable joints on FR4 pads

FAQ

Q: Can I cut this perfboard to a smaller size?
A: Yes — score with a hobby knife and snap, or use a PCB cutter. FR4 can also be cut with a rotary tool or fine-tooth saw.

Q: Are the pads connected in rows like a breadboard?
A: No — each pad is isolated. You must create connections by soldering wire bridges between pads. This gives full layout flexibility.
