Mezzanine Connectors (Board to Board)Mezzanine connectors are connectors that are used to connect two circuit boards together. They are commonly used in electronic devices that have multiple circuit boards, such as computers and smartphones, to allow the boards to communicate with each other and share information and power. Mezzanine connectors are typically designed to be small and compact, so they can be easily integrated into the design of the device. They are also often designed to be pluggable, so that the circuit boards can be easily connected and disconnected as needed.
