The board provides Arduino Uno revision 3 compatibility expansion header which comes with four
independent headers. The expansion header has 17 user pins (16pins GPIO and 1pin Reset)
connected directly to the MAX 10 FPGA. 6-pins Analog input connects to ADC, and also provides
DC +5V (VCC5), DC +3.3V (VCC3P3 and IOREF), and three GND pins.
