Morphology

circuit + board

The compound denotes a 'board' that contains or supports 'circuits', so its meaning is directly derivable from combining 'circuit' (route for electric current) with 'board' (a flat panel). This straightforward noun–noun composition follows common compounding patterns and has close equivalents in many languages, so a B1 learner who knows the parts will readily understand it.

Etymology

Circuit board comes from the simple image of a flat board where electronic parts sit and are joined by paths called circuits, so electricity can move between them. That's why it now means 'the flat piece inside a device that holds and connects its electronic parts'.
