Expansion Prototype Connectors
This section describes the expansion prototype connectors on the THDB-H2G board.
The THDB-H2G board has three expansion prototype connectors (JP1, JP2, and JP3) connected to the
HSMC connector directly. Each of the connectors has 36 prototyping I/Os and 3.3/5 volts power supply from
the HSMC interface and on-board regulator. In addition, the expansion connector is compatible with the
expansion headers of the Altera DE1/DE2 board. With these expansion connectors, users can connect the
Altera DE2/DE1 development kits or custom daughter boards to a HSMC-interfaced host board. Figure 3.4,
Figure 3.5, and Figure 3.6 shows the pin-outs of the expansion prototype connectors. Also, the detailed pin
mappings to HSMC connector are listed in Table 3.1, Table3.2, and Table 3.3.
