Expansion Prototype Connectors
This section describes the expansion prototype connectors on the THDB-HTG board.
The THDB-HTG board has three expansion prototype connectors (J2, J3, and J4) connected to the
HSTC/HSMC connector directly. Each of the connectors has 36 prototyping I/Os and 3.3/5 volts power supply
from the HSTC/HSMC interface and on-board regulator. In addition, the expansion connector is compatible
with expansion headers of Altera DE1/DE2 board. Users can connect Altera DE2/DE1 development kits or
custom daughter boards to a HSTC/HSMC-interfaced host board. Figure 3.2 and Figure 3.3 show the pin-outs
of the expansion prototype connectors for HSTC and HSMC version, respectively. Detailed pin mappings to
HSTC/HSMC connector are listed in Table 3.1, Table 3.2, and Table 3.3.
