Module with blue backlight, equipped with a connector Gravity is ideal for working with Arduino. The LED glows, when the pin signal switches to a low state. If the LED needs to be enabled when a high state, replace the signal wire (green) to ground (black) and power cable (red) from the original location of the signal.
The kit includes a cable adapted to Gravity DFRobot IO Expansion Shield.
