Circuit Pad for External Connection
The circuit pad located on the right side of the evaluation boards (NE-4100-ST and NE-4110-ST)
is used to develop additional application circuits. The circuit pad is circled in red in the figure
below. As shown in the second figure, the first row of the circuit pad is for connecting a 5V power
supply, whereas the second row is for connecting a 3.3V power supply. J3’s and J9’s header
pinouts are exactly the same, which means that J3’s pin 1 corresponds to J9’s pin 1, pin 2
corresponds to pin 2, etc. J4’s pinouts are the same as J10’s, which means that J4’s pin 1
corresponds to J10’s pin 1. The last row of the circuit pad is for grounding.
