Electronics hobbyists, this 5-pack of universal PCB boards is perfect for all your DIY projects. Each board measures 100x220mm (about 3.94x8.66 inches) and features a double-sided design with pre-tinned holes that make soldering components so much easier. The glass fiber FR-4 material is industry standard quality - durable, heat-resistant, and perfect for both prototyping and final projects. With 38x80 holes arranged in a 2.54mm pitch pattern, you've got plenty of space for even complex circuits. The 1mm hole diameter accommodates most component leads, and the 3mm mounting holes make securing the board simple. The pre-tinned holes are solid and won't lift during soldering, which is a huge plus compared to cheaper boards. These are ideal for transferring your breadboard designs to a permanent circuit without having to recut wires or change your layout. Whether you're building Arduino projects, audio amplifiers, LED displays, or learning electronics, these boards provide a professional foundation for your creations. The green solder mask with silver tone pads looks sharp, and the 1.6mm thickness gives them substantial durability. Having five boards means you can work on multiple projects simultaneously or have spares for when you make mistakes - because let's be real, we all make soldering mistakes sometimes!
