The board provides one 40-pin expansion header (GPIO) and one Arduino Uno R2 expansion
header. These two kinds of expansion headers share parts of the IO. In addition, GPIO share I/O
with 7-Segment Display. Please refer to
. for detailed connections and block diagrams.
Figure 3-24 Connections between FPGA / GPIO / Arduino and 7-Segment display (share bus)
Now we introduce the 40-pin expansion header (GPIO) and Arduino Uno R2 expansion header.
