3-8 Using the Expansion Headers
The DE2 Board provides users two 40-pin expansion headers. Each header
provides DC +5V (VCC5), DC +3.3V (VCC33), two GND pins for users to build
their own daughter cards using the DE2 expansion ports.
Figure 3.10 shows the related schematics. The pin assignment of the associated
interface is shown in Table 3.8.
