4.9.2. 2x20 GPIO Expansion Header

The Intel® Cyclone® 10 LP FPGA evaluation board provides one 40-pin expansion GPIO header with up to 36 GPIO signals. This 2x20 GPIO Header is compatible with some Terasic 2x20 GPIO cards.

There are also +5 V (VCC_5V_GPIO) and +3.3 V (VCC_3.3V) and two GND pins on 2x20 GPIO expansion header. All GPIO signals GPIO[0:35] are 3.3 V single-ended LVCMOS/LVTTL signals who are connected to Intel® Cyclone® 10 LP FPGA directly.

The maximum power output capability is shown in the table below. When using 2x20 GPIO Header, USB may not provide sufficient power. Hence, use an external adapter connector (J12) to power up the board.
