What is Daughter Board

A daughter board, also known as a daughter card or daughtercard, is a smaller printed circuit board that connects to the main circuit board, such as a motherboard or expansion card, in a computer hardware system. It is designed to extend the functionality or add specialized features to the main board.

Unlike expansion cards, which are separate components that add new functions to a computer, a daughter board is directly connected to the main board through soldering or a socket. It serves as an update or enhancement to the existing motherboard or expansion card, providing additional capabilities or supporting the main functions of the system.

Daughter boards are commonly used in the PCB industry to expand the capabilities of existing circuit boards. They can be used to incorporate additional components, such as RAM or CPUs, or to add specialized circuitry for specific purposes. By connecting to the main board, daughter boards offer a modular approach to system design, allowing for customization and flexibility in upgrading or replacing components.
