Part 3.9: 40-Pin Expansion Port
The AV7K325 FPGA development board is reserved with one 0.1 inch
spacing standard 40-pin expansion port J18, which is used to connect the
ALINX modules or the external circuit designed by the user. The expansion port
has 40 signals, of which 1-channel 5V power supply, 2-channel 3.3 V power
supply, 3-channle ground and 34 IOs.
Do not directly connect the IO directly
to the 5V device to avoid burning the FPGA. If you want to connect 5V
