[32-piece set in various sizes] Universal, double-sided experiment and learning set with through-holes (including 2x8, 3x7, 4x6, 5x7, 7x9cm), suitable for electronic soldering exercises.--DTEKGAZ

[32-Piece Value Pack]: This value pack contains 32 universal, double-sided printed circuit boards (PCBs) in 5 different sizes: 2 x 8 cm, 3 x 7 cm, 4 x 6 cm, 5 x 7 cm, and 7 x 9 cm. It covers a wide range of prototyping needs, from micro modules to medium-sized circuits, and saves you the cost of purchasing individual PCBs for each project. [Double-Sided Through-Plug Technology]: Manufactured on a high-quality FR-4 fiberglass substrate, these PCBs feature double-sided copper plating and through-hole technology (TPT). The conductive perforations facilitate soldering and routing on both sides of the board, enabling more complex and robust circuit connections—essential for reliable prototyping. [Standard Pad Layout]: The PCBs feature a standard 2.54 mm (0.1 in) pad layout. This kit is perfectly compatible with common through-hole components (DIP chips, resistors, capacitors, connectors, sockets, etc.) and most standard grid assemblies, enabling intuitive and convenient layout planning. [Essential for Electronics Learners and DIY Projects]: Whether you're a beginner practicing soldering techniques, an electronics enthusiast, an electronics student working on course projects or prototypes for your final year, or an engineer validating circuit ideas, this multi-sized universal PCB kit is an essential and practical tool. It allows you to quickly create your circuit designs without relying on custom-made circuit boards, saving you time and money. [Flexible and Adaptable]: You can freely choose the board size depending on the complexity of your circuit, or connect multiple small boards to create a larger one using connectors or wires. Available in various sizes, this kit offers great flexibility for your designs. It's an ideal and readily available consumable for manufacturing workshops and electronics labs.
