Control boards, also known as circuit boards or printed circuit boards (PCBs), are a vital component of modern electronic devices. These boards are responsible for managing and regulating the flow of electricity through a device, allowing it to function properly. Other synonyms for control boards include motherboard, logic board, CPU board, and system board. Some devices also have specialized control boards, such as power control boards or display control boards. Control boards come in various sizes and configurations, from small boards in handheld devices to large boards in industrial machinery. Regardless of their size or function, control boards remain a key component of electronic devices, enabling them to operate efficiently and reliably.
