Part 3.8: Expansion Header
The AXU4EV-E board is reserved with two 0.1-inch standard pitch 40-pin
expansion ports J45 and J46, which are 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 equipment, you
need to connect level conversion chip.
