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.
