Table 1. Arduino connectors pin chart and usage
The circuit is supplied from Arduino port through J6 and J4. Pin 4 of J6 is a 3.3 V power
supply while pin 5 of J6 is a 5 V power supply. Pins 6 and 7 of J6, and pin 7 of J4
represents the power supply return (ground).
shows the Arduino connectors. See also the SPF-46655_B.pdf schematic file of
NTS0304EUK-ARD daughterboard.
