IV. Application wiring diagram.

WS2811 mini controller

1. Wiring

The controller has three leads, of which red represents the positive power line (VCC), white (two: respectively, signal ground and power ground) represents the ground line (GND), green represents the pin signal line (DIN).

Microcontroller and light string connection: 3 leads are connected correspondingly, generally the red, white and green of the microcontroller and the positive, signal and negative of the light string correspond to each other.

Then the red wire is connected to the positive terminal of the external DC power supply, and the black wire is connected to the negative terminal of the external DC power supply, that is, the external DC power supply both to the microcontroller and to the light string.

2. Operation instructions

Before powering on, observe whether the power supply is the same as the working voltage of the controller (the controller has two kinds of 5V and 12V), and make sure there is no short circuit between the connection lines.

The mini controller has 3 buttons.
