Prototype printed circuit board component

　　Prototype printed circuit board (PCB) components refer to printed circuit boards used for developing and testing electronic circuits. This type of PCB typically has a universal design that allows users to install various electronic components such as resistors, capacitors, transistors, etc. on it. Compared with traditional circuit boards, prototype PCBs have higher flexibility and scalability, allowing engineers to try multiple circuit design solutions on one platform.

　　Prototype PCB components typically include basic wiring patterns, solder pads, and vias for easy soldering and connection of components. In addition, some advanced prototype PCBs may also include pre fabricated circuit modules, such as power management modules, sensor interfaces, etc., which can greatly simplify the circuit design process and improve development efficiency.
