WLED FAQ

  • Which microcontroller types are supported by WLED software?
  • How many LEDs can a WLED controller control?

    ESP8266 based controllers can control up to approx. 600-650 LEDs. ESP32-based controllers can control up to 4,000 LEDs. However, it is recommended to distribute LED strips over several inputs so that no more than 1000 LEDs are connected to one input: many LEDs n one output lead to the control rate dropping and irregularities being seen with fast effects. When using some transmission protocols, it must also be taken into account that they may only support a limited number of LEDs.

  • Is a LevelShifter really needed in WLED controller?
  • Which LevelShifters are recommended?
  • Does a resistor have to be installed in the data line between the WLED controller and the LED strip? Which one?
  • Is a ready-made WLED controller recommended, or can one be assembled from individual components?
  • Can I connect a button to a WLED controller? How?
  • How many buttons can be connected to a WLED controller?
  • Is it possible to connect a motion detector (PIR sensor) to a WLED controller?
  • Can a WLED controller be controlled with a remote control?
  • Can the WLED Controller be connected via Ethernet (LAN) instead of wireless?
