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.

The physical size of a large system may require that expandability be accomplished using an alternate chassis, while in a small system the expandability must be done as mezzanine boards on a single slot card.
Two boards, a PMC mezzanine board ($2,100) or a PCI add-in card ($1,750), operate on full frames in both PAL and NTSC format.
All of the relays are located on the main board with the user adding specific loads to the mezzanine board. The card also provides parallel and serial control interfaces which can be used by the end user to control specific circuitry on the mezzanine board.
The mezzanine board supports all connections to the UUT via two 78-pin D-sub connectors.
A mezzanine board incorporates a clock distribution circuit allocating in-phase, anti-phase, or quadrature clocks to support interleaved sampling rates at up to 2 GS/s.
An alternative to vendor-specific PHY interface solutions is the VITA 57 FPGA Mezzanine Card (FMC) standard, which standardizes both the physical and electrical interfaces to FPGAs, resulting in the availability of a portfolio of off-the-shelf mezzanine boards and a standardized method for interfacing to these boards via a defined connector interface.
According to the firm, mezzanine boards can be added to the printed circuit board assembly stack to add functionality, such as translation and haptic electronics.
