LED: there is an onboard LED, please connect the LED to Digital pin 13 (D13).
D&A: new version IO expansion shield printed with "D" and "A".
"D": Represents a digital signal. That is, connect to the digital pins of mainboard.
"A": Represents an analog signal. That is, connect to the analog pins of mainboard.
Compared with limited power-supply interfaces in mainly mainboards, IO Expansion Shield increase a large amount of power-supply interfaces and GND pins. Therefore, users no need to worry about the shortage of power supply interfaces when connecting many modules.
Special description of the color distinction in DF:
| Color | Function |
|---|---|
| Green | Digital Signal |
| Blue | Analog Signal |
| Red | VCC(+) |
| Black | GND(-) |
