Product Description (Detailed):
Unlock endless possibilities for your electronic projects with our versatile Zero PCB 3x4 Inch General Purpose Grid PCB. Also known as a perfboard or DOT PCB, this essential prototyping tool provides a blank canvas for assembling custom circuits without the need for complex custom PCB fabrication. Measuring a convenient 3x4 inches (approximately 7.5cm x 10cm), it features a standardized 2.54mm (0.1-inch) hole pitch, ensuring seamless compatibility with a vast array of common electronic components, including ICs, resistors, capacitors, and various through-hole connectors. Each pre-drilled hole is surrounded by a conductive copper pad, facilitating easy and reliable soldering of components for a more permanent and robust circuit compared to temporary breadboard setups. Typically constructed from durable FR-4 glass epoxy or phenolic laminate, this general purpose PCB offers excellent electrical insulation and mechanical stability. Whether you're a student learning fundamental circuit design, a hobbyist building a unique gadget, or an engineer rapidly prototyping a concept, this through-hole prototyping board is indispensable. Its grid layout simplifies circuit planning and allows for flexible component placement, making it an ideal choice for developing embedded systems, small modules, or repairs where a custom PCB isn't practical.
The 3x4 Grid PCB (Perfboard) is a general-purpose prototype board used for building and testing custom circuits. With standard 2.54mm spacing, it's compatible with a wide range of components including ICs, resistors, capacitors, connectors, and Arduino modules.
This perfboard is commonly used by students, hobbyists, and engineers for quick prototyping before final PCB design. The compact size (3 inch × 4 inch) fits well in most project enclosures and development boards.
