QUICK START GUIDE
1. Connect the LED board to the WLED driver following the pinout.
2. Preset power supply output to 7V to 21V and turn off the power supply.
3. Connect the positive terminal of the power supply output to VIN pin, and the negative terminal of
the power supply output to GND pin.
4. Turn power supply on and the board will automatically startup.
5. To use Enable function, apply a digital input to EN pin. Drive EN with 2.5V-5V to turn off the
regulator, and drive EN less than 0.7V to turn it on.
6. To use Dim function, apply a 1KHz PWM signal to DIM pin (High > 4V – 5V, Low < 0.5V).
Change the duty cycle to adjust the brightness level.
