Duo2Go Setup Instructions

While these controllers come with WLED preinstalled, you can download the firmware here if you ever need to reinstall:

WLED 0.13.3  - Compiled for Duo2Go v1.x
(It is NOT recommended to install 0.14 on the Duo2Go, as this version has issues with the ESP8266 when you connect to a local wireless network. If you must install 0.14, do NOT connect the Duo2Go to your local Wi-Fi network. Connect to it instead using the built-in AP)

You will also need the following software installed to image the ESP8266:

  1. Configure the Correct Voltage
    Your lights should match the DC voltage output of your power supply. The Duo2Go supports either 5V or 12V pixels.

    It is CRITICAL that you select the proper voltage using this jumper. An incorrect setting could damage your Duo2Go and/or your LEDs.

  2. Connect your Power Supply

    Carefully connect the voltage and ground lines from your DC power supply to the power connector (J1). Take care to ensure the polarity is correct. The Voltage (V+) should be plugged into the 5V/12V side and Ground (V-) should be screwed into the GND side.
    Make SURE you have the wires connected properly. If your wires are reversed you could damage your Duo2Go and/or your LEDs.

    As soon as you power on your power supply, you will see a blue LED lit on the ESP8266 and the board will begin to boot WLED.

    If you see a red LED lit on the controller, you have connected the DC power backwards. Unplug power and wait for the red LED to go out. Then connect the DC power cable correctly and try again.

    * Make sure to note that the reverse-protection circuit only safeguards the controller and not any attached LEDs. Keep in mind that if polarity is reversed, any connected LEDs may still be damaged. After connecting the DC power cable, ALWAYS try to power on the controller without any pixels first to ensure proper polarity.

  3. Connect your LEDs

    Remove the male connectors from the two Phoenix connectors on the bottom of the board.  Insert the wires from your LED string into one of the connectors, carefully ensuring that your Voltage (V), Data (D) and Ground (G) wires match the diagram above.

  4. Loading WLED for the first time
    1. Browse for wireless networks using your WIFI-enabled computer or smartphone. Look for an SSID called "WLED-AP-Duo2Go"

    2. Connect to that network. If prompted, the password is wled1234

    3. A browser should pop up showing the WLED intro screen. If not, browse manually to

     If you are eager to get started, you can configure lights by simply clicking on the "To the Controls!" button, but we recommend connecting the device to your local LAN so that you can set an IP and/or hostname so that you can easily control the lights later. Click on "WIFI Settings" to do this.

    Make sure you set the correct SSID and Network password for your wireless network.

    (* - Make sure your SSID does not include spaces or special characters like an apostrophe. WLED may have trouble connecting to these. We recommend you remove any spaces or special characters from your wireless SSID before trying to connect WLED)

    Then, if you want a static IP address, populate the following fields with the appropriate IP address, Gateway, and Subnet Mask. Once this is set, you can easily browse to the Duo2Go via your computer's web browser. Just type in the new IP address in the URL bar.

  5. Installing the App
    If you do not know how to set a static address, it is usually safe to allow your router to assign this automatically using DHCP.  WLED will default to DHCP if you do not enter any specific IP address information.

        So - how do you find the IP address that the Duo2Go was assigned? Probably the easiest way is to install the WLED app on your Android or Apple phone.


    (Note! It appears that the official WLED app is no longer available for download on the Apple store. In it's place you can use the WLED-native app)


        When you start the app, click the "+" button in the upper right corner to add a new controller and then press the "Discover Lights" button to search for your new Duo2Go.

      Assuming your network is set up correctly, the Duo2Go should be detected. Enter a custom name below to name your device and press the check mark in the upper right corner to complete the discovery.

    You should then see a list of all of the WLED controllers on your network, along with their IP addresses.


    Click on the controller name to connect to the controller:


  6.  Configuring your LEDs and their Color Order

    By default, the Duo2Go is configured to output to 100 pixels on both ports 1 and 2. When you connect your lights, they should light up with an orange color. This is completely normal.

    Most bullet pixels are "RGB" pixels.  That is the default setting for the Duo2Go controller. If you find the colors not lining up properly you may have to change the "Color Order" setting.

    Here's how you can find your correct color order:
    * Write the letters "RGB" on a piece of paper.
    * Then - set your lights to RED. What color appears? Write the first letter of this color (R,G or B) under the "R".
    * Next, set your lights to GREEN. Write the first letter of this color under the "G".
    * Finally, set your lights to BLUE. Write the first letter of this color under the "B".

    The three letters will form the new color order that you need to choose to make your lights work properly.  In this example, the color order should be "BGR". You can save this new setting in "Config -> LED Preferences -> Hardware Setup -> LED outputs (1 & 2) -> Color Order.

    Finally, press SAVE.
