daughterboard

(hardware)
(Or "daughter board", "daughtercard", "daughter card") A printed circuit board that connects to the motherboard. The daughterboard is typically smaller than the motherboard.

A daughterdboard often adds to or supports the main functions of the motherboard, unlike an expansion card which provides some new function. For example, a post-release hardware modification might be released as a daughterboard for soldering onto the motherboard.

daughterboard

A printed circuit board that plugs into another printed circuit board, which plugs into the main board (motherboard). Daughterboards, also called "mezzanine cards," augment the capabilities of the card they plug into. See mezzanine card.
