Circuit Daughterboard :
A Circuit Daughterboard is a compact, modular printed circuit board (PCB) designed to connect to a main motherboard or baseboard to extend, enhance, or customize its functionality. Daughterboards typically offer specific features such as additional input/output interfaces, communication ports, sensors, or specialized processing components. These boards are widely used in embedded systems, prototyping platforms, industrial control systems, and consumer electronics to provide scalable and flexible hardware design.
