Universal Prototype PCB Board 4×6cm — Double-Sided FR4 for Electronics Projects

Universal Prototype PCB Board — 4×6 cm, Double-Sided FR4

The 4×6 cm universal prototype PCB board is the small form-factor prototyping board — perfect for sensor breakout circuits, Arduino Nano builds, and compact single-stage designs that need to fit in tight enclosures or wearable projects. 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, and connectors without adapters.

Key Features

• 4×6 cm working area — small form factor, ideal for sensor breakouts and compact circuit builds
• 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 and pin headers
• Tin-plated through-holes — excellent solderability, corrosion-resistant pads

Typical Applications

• Sensor breakout and interface circuit assembly
• Arduino Nano and Pro Mini compact builds
• Small power supply and regulator circuits
• Wearable and embedded electronics prototyping
• Custom PCB replacement for compact electronics
