The THDB-H2G (HSMC to GPIO Daughter Board) board is designed to fan out the High Speed Mezzanine connector (HSMC) I/Os to three 40-pin expansion prototype connectors, which are compatible with Altera DE2/DE1/DE0 expansion headers. Users can connect up to three Altera DE2/DE1/DE0 boards (or associated daughter cards) onto a HSMC-interfaced host board via the THDB-H2G board.
