PCB FR4 Circuit Board (7 x10) cm single layer

From the shop's description

PCB FR4 Circuit Board (7 x10) cm single layer is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. FR4 Copper Clad Plate Laminate Single Side PCB is a glass fiber epoxy resin-based PCB with copper foil on one side. The epoxy glass fiber forms the substrate on which the copper foil is hot pressed only on one side and the other side remains bare. It has a copper core for strength and the substrate acts as electrical insulation. The PCB is ideal for prototyping and experimenting. This PCB can almost be seen in electronic equipment like electronic watches, calculator, computers, communication electronic equipment, military weapon system, etc. As long as there are integrated circuits and other electronic devices, electrical interconnection between them will require the use of this type of PCB. Note: 1. The PCB may have scratches as it is cleaned before shipping. 2. The product dimensions may vary from the images. Features: Foil: Copper. Ideal for prototyping. It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
