DE2-115 Datasheet, PDF (47/116 Pages) Altera Corporation – The DE2-115 package contains all components needed to use the DE2-115 board in conjunction with a computer that runs the Microsoft Windows OS.

GND pins. Figure 4-15 shows the I/O distribution of the GPIO connector. The maximum power
consumption of the daughter card that connects to GPIO port is shown in Table 4-10.

Each pin on the expansion headers is connected to two diodes and a resistor that provides protection
against high and low voltages. Figure 4-16 shows the protection circuitry for only one of the pin on
the header, but this circuitry is included for all 36 data pins.
